AME385-2.5
n n n n n
The AME385-2.5 is a micropower 2-terminal band-gap
voltage regulator diode. It operates over a 20 A to 20mA
current range. Each circuit is trimmed at wafer sort to
provide a 0.20% and 0.50% 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
current makes these part ideal for battery applications.
Analog Microelectronics offers this part in a TO-92 and
SO-8 package as well as the space saving SOT-23.
