n General Description

nn

The AME41-1.2 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 ±0.20% and ±0.50% initial tolerance. The de­sign of the AME41-1.2 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.
