LM185-1.2/LM285-1.2/LM385-1.2

Micropower Voltage Reference Diode

The LM185-1.2 is rated for operation over a −55˚C to 125˚C

temperature range while the LM285-1.2 is rated −40˚C to

85˚C and the LM385-1.2 0˚C to 70˚C. The LM185-1.2/

LM285-1.2 are available in a hermetic TO-46 package and

the LM285-1.2/LM385-1.2 are also available in a low-cost

TO-92 molded package, as well as SO and SOT-23. The

LM185-1.2 is also available in a hermetic leadless chip car-

rier package.

General Description

The LM185-1.2/LM285-1.2/LM385-1.2 are micropower

2-terminal band-gap voltage regulator diodes. Operating

over a 10 µA to 20 mA current range, they feature exception-

ally low dynamic impedance and good temperature stability.

On-chip trimming is used to provide tight voltage tolerance.

Since the LM185-1.2 band-gap reference uses only transis-

tors and resistors, low noise and good long term stability re-

sult.

Features

Careful design of the LM185-1.2 has made the device ex-

ceptionally 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.

4 mV ( 0.3 ) max. initial tolerance (A grade)

n Operating current of 10 µA to 20 mA

n 0.6Ω max dynamic impedance (A grade)

n Low temperature coefficient

n Low voltage reference — 1.235V

n 2.5V device and adjustable device also available

n LM185-2.5 series and LM185 series, respectively

The extremely low power drain of the LM185-1.2 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.
