FEATURES

DESCRIPTION

Ideal for space critical applications, the LM4128

2

•

Output Voltage Initial Accuracy 0.1%

precision voltage reference is available in the SOT-23

•

Low Temperature Coefficient 75 ppm/°C

surface-mount package. The LM4128’s advanced

•

Low Supply Current, 60 µA

design eliminates the need for an external stabilizing

capacitor while ensuring stability with capacitive loads

•

Enable Pin Allowing a 3 µA Shutdown Mode

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

•

Up to 20 mA Output Current

Series references provide lower power consumption

•

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

than shunt references, since they do not have to idle

4.096V

the maximum possible load current under no load

•

Custom Voltage Options Available (1.8V to

conditions. This advantage, the low quiescent current

4.096V)

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

the LM4128 ideal for battery-powered solutions.

•

•

Stable with Low ESR Ceramic Capacitors

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

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