LM385/LM385B

Adjustable Micropower Voltage Reference

FEATURES

DESCRIPTION

The LM385 is micropower 3-terminal adjustable

l Adjustable from 1.24V to 5.3V.

l Operating Current from 10mA to 20mA.

l Low Temperature Coefficient.

l 1% and 2% Initial Tolerance.

l Low Dynamic Impedance.

band-gap voltage reference. Operating from

1.24V to 5.3V and over 10mA to 20mA current

range. They feature exceptionally low dynamic

impedance and good temperature stability. On-

chip trimming is used to achieve tight voltage

tolerance. Since the LM385 band-gap reference

uses only transistors and resistors, low noise

and good longterm stability result.

APPLICATIONS

l Portable, Battery-Powered Equipment.

l Instrumentation.

Careful design of the LM385 has made the de-

vice tolerant of capacitive loading, making it

easy to use in almost any reference application.

The wide dynamic operating range allows its

use with widely varying supplies with excellent

regulation.

l Process Control.

l Energy Management.

l Product Testing.

l Automotive.

l Precision Audio Components.

TYPICAL APPLICATION

CIRCUIT

The extremely low power drain of the LM385

makes it useful for micropower circuitry. This

voltage reference can be used to make portable

meters, regulators or general purpose analog

circuitry with battery life approaching shelf life.

Further, the wide operating current allows it to

replace older references with a tighter tolerance

part.
