Datasheet
n General Description
voltage regulator diode. It operates over a 30 A to 20mA
current range. Each circuit is trimmed at wafer sort to
provide a ± 0.5% initial tolerance. The design of the
AME385-1.2 allows for a large range of load capacitances
and operating currents. The low start-up current makes
these parts ideal for battery applications.
