General Description
The AME40 is a micropower 2-terminal band-gap volt-
age 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 de-
sign of the AME40 allows for a large range of load capaci-
tances 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.
