General Description
The AME41-1.2 is a micropower 2-terminal band-gap
voltage regulator diode. It operates over a 30µA to 20mA
current range. Each circuit is trimmed at wafer sort to
provide a ± 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 parts ideal for battery applications.
AME offers this part in a TO-92 and SOP-8 packages
as well as the space saving SOT-23.
