Micropower Voltage Reference Diode

AME385-1.2

n General Description

n Functional Block Diagram

The AME385-1.2 is a micropower 2-terminal band-gap

voltage regulator diode. It operates over a 15mA to 20mA

current range. Each circuit is trimmed at wafer sort to

provide a ±0.2% and ±0.5% initial tolerance. The design

of the AME385-1.2 allows for a large range of load capaci-

tances and operating currents. The low start-up current

makes these part ideal for battery applications.

Analog Microelectronics offers this part in a TO-92 and

SO-8 packages as well as the space saving SOT-23.
