Micropower Voltage Reference Diode
AME41-ADJ
n General Description
n Key Features
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.
