AME385-1.2

Micropower Voltage Reference Diode

General Description

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

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

current range. Each circuit is trimmed at wafer sort to

provide a

±0.2%

and

±0.5%

initial tolerance. The de-

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

capacitances 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.

Key Features
