Micropower Voltage Reference Diode

AME385-2.5

n General Description

n Functional Block Diagram

The AME385-2.5 is a micropower 2-terminal band-gap

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

current range. Each circuit is trimmed at wafer sort to

provide a ±0.20% and ±0.50% initial tolerance. The de-

sign of the AME385-2.5 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 package as well as the space saving SOT-23.
