LM4120

Precision Micropower Low Dropout Voltage Reference

General Description

The LM4120 is a precision low power low dropout bandgap

voltage reference with up to 5 mA output current source and

sink capability.

This series reference operates with input voltages as low as

2V and up to 12V consuming 160 µA (Typ.) supply current. In

power down mode, device current drops to less than 2 µA.

The LM4120 comes in two grades (A and Standard) and

seven voltage options for greater flexibility. The best grade

devices (A) have an initial accuracy of 0.2%, while the stan-

dard have an initial accuracy of 0.5%, both with a tempco of

50ppm/˚C guaranteed from −40˚C to +125˚C.

The very low dropout voltage, low supply current and power-

down capability of the LM4120 makes this product an ideal

choice for battery powered and portable applications.

The device performance is guaranteed over the industrial

temperature range (−40˚C to +85˚C), while certain specs are

guaranteed over the extended temperature range (−40˚C to

+125˚C). Please contact National for full specifications over

the extended temperature range. The LM4120 is available in

a standard 5-pin SOT-23 package.
