AME385AEHA

AME AME385-1.2 n General Description The AME385-1.2 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 ± 0.5% 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. AME offers this part in a TO-92 and SOP-8 packages as well as the space saving SOT-23.
