AME385-2.5
Shunt Bandgap Voltage Reference
n General Description
The AME385-2.5 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% and ± 0.80% initial tolerance. The de-
sign of the AME385-2.5 allows for a large range of load
capacitances and operating currents. The low start-up cur-
rent 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.
