LM4128

SOT-23 Precision Micropower Series Voltage Reference

General Description

Features

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 sta-

bility 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

Voltage options 1.8V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V

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 advan-

tage, the low quiescent current (60 µA), and the low dropout

voltage (400 mV) make the LM4128 ideal for battery-powered

solutions.

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

■

SOT23-5 Package

−40°C to 125°C junction temperature range

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 guaranteed 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.
