AME40
n n n n n
The AME40 is a micropower 2-terminal band-gap voltage
regulator diode. It operates over a 40 A to 20mA current
range. Each circuit is trimmed at wafer sort to provide a
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.
