AME AME41AEET Micropower voltage reference diode Datasheet

Analog Microelectronics, Inc.
Micropower Voltage Reference Diode
AME41-1.2
n General Description
n Key Features
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.
