AME41-ADJ
Micropower Voltage Reference Diode

General Description
The AME41-ADJ is a micropower 3-terminal band-gap
voltage regulator diode with a user adjustable output volt-
age. 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-
ADJ 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.
