AME385-1.2

n n n n n

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

voltage regulator diode. It operates over a 15 A 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.
