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 ± 0.50% initial tolerance. The design of the
AME40 allows for a large range of load capacitances and
operating currents. The low start-up current makes these
parts ideal for battery applications.
AME offers this part in a TO-92, SOP-8 packages as
well as the space saving SOT-23.
