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