AME AME41-ADJ n General Description The AME41-ADJ is a micropower 3-terminal band-gap voltage regulator diode with a user adjustable output voltage. 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-ADJ 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.
