LM4128/LM4128Q SOT-23 Precision Micropower Series Voltage Reference

Check for Samples: LM4128, LM4128Q

FEATURES

DESCRIPTION

Ideal for space critical applications, the LM4128

precision voltage reference is available in the SOT-23

surface-mount package. The LM4128’s advanced

design eliminates the need for an external stabilizing

capacitor while ensuring stability with capacitive loads

up to 10 μF, thus making the LM4128 easy to use.

Output Voltage Initial Accuracy 0.1%

Low Temperature Coefficient 75 ppm/°C

Low Supply Current, 60 μA

Enable Pin Allowing a 3 μA Shutdown Mode

Up to 20 mA Output Current

Series references provide lower power consumption

than shunt references, since they do not have to idle

the maximum possible load current under no load

conditions. This advantage, the low quiescent current

(60 μA), and the low dropout voltage (400 mV) make

the LM4128 ideal for battery-powered solutions.

Voltage Options 1.8V, 2.048V, 2.5V, 3.0V, 3.3V,

4.096V

Custom Voltage Options Available (1.8V to

4.096V)

V_INRange of V_REF+ 400 mV to 5.5V @10 mA

Stable with Low ESR Ceramic Capacitors

5-Pin SOT-23 Package

The LM4128 is available in four grades (A, B, C, and

D) for greater flexibility. The best grade devices (A)

have an initial accuracy of 0.1% with ensured

temperature coefficient of 75 ppm/°C or less, while

the lowest grade parts (D) have an initial accuracy of

1.0% and a tempco of 100 ppm/°C.

?40°C to 125°C Junction Temperature Range

(1) Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. Operating Ratings indicate conditions for

which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications, see Electrical

Characteristics.

(2) Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by T_JMAX

(maximum junction temperature), θ_J-A(junction to ambient thermal resistance) and T_A(ambient temperature). The maximum power

dissipation at any temperature is: P_DissMAX= (T_JMAX- T_A) /θ_J-Aup to the value listed in the Absolute Maximum Ratings. θ_J-Afor SOT-23

package is 220°C/W, T_JMAX= 125°C.

(3) The human body model is a 100 pF capacitor discharged through a 1.5 k? resistor into each pin.

APPLICATION INFORMATION

THEORY OF OPERATION

The foundation of any voltage reference is the band-gap circuit. While the reference in the LM4128 is developed

from the gate-source voltage of transistors in the IC, principles of the band-gap circuit are easily understood

using a bipolar example. For a detailed analysis of the bipolar band-gap circuit, see the AN-56 Application Report

(SNVA514).

SUPPLY AND ENABLE VOLTAGES

To ensure proper operation, V_ENand V_INmust be within a specified range. An acceptable range of input voltages

V_IN> V_REF+ 400 mV (I_LOAD≤ 10 mA)

(1)

The enable pin uses an internal pull-up current source (I_{PULL_UP}? 2 μA) that may be left floating or triggered by

an external source. If the part is not enabled by an external source, it may be connected to V_IN. An acceptable

range of enable voltages is given by the enable transfer characteristics. See the Electrical Characteristics section

and Enable Transfer Characteristics figure for more detail. Note, the part will not operate correctly for V_EN> V_IN.

COMPONENT SELECTION

A small ceramic (X5R or X7R) capacitor on the input must be used to ensure stable operation. The value of C_IN

must be sized according to the output capacitor value. The value of C_INmust satisfy the relationship C_IN≥ C_OUT

When no output capacitor is used, C_INmust have a minimum value of 0.1 μF. Noise on the power-supply input

may affect the output noise. Larger input capacitor values (typically 4.7 μF to 22 μF) may help reduce noise on

the output and significantly reduce overshoot during startup. Use of an additional optional bypass capacitor

between the input and ground may help further reduce noise on the output. With an input capacitor, the LM4128

will drive any combination of resistance and capacitance up to V_REF/20 mA and 10 μF respectively.

The LM4128 is designed to operate with or without an output capacitor and is stable with capacitive loads up to

10 μF. Connecting a capacitor between the output and ground will significantly improve the load transient

response when switching from a light load to a heavy load. The output capacitor should not be made arbitrarily

large because it will effect the turn-on time as well as line and load transients.

While a variety of capacitor chemistry types may be used, it is typically advisable to use low esr ceramic

capacitors. Such capacitors provide a low impedance to high frequency signals, effectively bypassing them to

ground. Bypass capacitors should be mounted close to the part. Mounting bypass capacitors close to the part will

help reduce the parasitic trace components thereby improving performance.

SHORT CIRCUITED OUTPUT

The LM4128 features indefinite short circuit protection. This protection limits the output current to 75 mA when

the output is shorted to ground.

TURN ON TIME

Turn on time is defined as the time taken for the output voltage to rise to 90% of the preset value. The turn on

time depends on the load. The turn on time is typically 33.2 μs when driving a 1μF load and 78.8 μs when driving

a 10 μF load. Some users may experience an extended turn on time (up to 10 ms) under brown out conditions

and low temperatures (-40°C).

THERMAL HYSTERESIS

Thermal hysteresis is defined as the change in output voltage at 25oC after some deviation from 25oC. This is to

say that thermal hysteresis is the difference in output voltage between two points in a given temperature profile.

An illustrative temperature profile is shown in Figure 16.

where

T_D= Temperature drift

V_REF= Nominal preset output voltage

V_{REF_MIN}= Minimum output voltage over operating temperature range

V_{REF_MAX}= Maximum output voltage over operating temperature range

ΔT = Operating temperature range

(3)

The LM4128 features a low temperature drift of 75 ppm (max) to 100 ppm (max), depending on the grade, from -

40°C to 125°C.

LONG TERM STABILITY

Long-term stability refers to the fluctuation in output voltage over a long period of time (1000 hours). The LM4128

features a typical long-term stability of 50 ppm over 1000 hours. The measurements are made using 5 units of

each voltage option, at a nominal input voltage (5V), with no load, at room temperature.

EXPRESSION OF ELECTRICAL CHARACTERISTICS

Electrical characteristics are typically expressed in mV, ppm, or a percentage of the nominal value. Depending

on the application, one expression may be more useful than the other. To convert one quantity to the other one

may apply the following:

ppm to mV error in output voltage:

V_REFx ppm_ERROR

= V_ERROR

10³

where

V_REFis in volts (V) and V_ERRORis in milli-volts (mV)

(4)

Bit error (1 bit) to voltage error (mV):

V_REF

2ⁿ

x 10³

= V_ERROR

where

V_REFis in volts (V)

V_ERRORis in milli-volts (mV)

and n is the number of bits

(5)

PRINTED CIRCUIT BOARD and LAYOUT CONSIDERATIONS

References in SOT packages are generally less prone to PC board mounting than devices in Small Outline

(SOIC) packages. To minimize the mechanical stress due to PC board mounting that can cause the output

voltage to shift from its initial value, mount the reference on a low flex area of the PC board, such as near the

edge or a corner.

The part may be isolated mechanically by cutting a U shape slot on the PCB for mounting the device. This

approach also provides some thermal isolation from the rest of the circuit.

Bypass capacitors must be mounted close to the part. Mounting bypass capacitors close to the part will reduce

the parasitic trace components thereby improving performance.
