n General Description

nn

The AME40 is a micropower 2-terminal band-gap voltage
regulator diode. It operates over a 40µA 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
AME40 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,
SO-8 packages as well as the space saving SOT-23.
