Micropower Voltage Reference Diode

AME385-1.2

n General Description

n Key Features

The AME385-1.2 is a micropower 2-terminal band-gap

voltage regulator diode. It operates over a 15µA to 20mA

current range. Each circuit is trimmed at wafer sort to

provide a ±0.2% and ±0.5% initial tolerance. The de-

sign of the AME385-1.2 allows for a large range of load

capacitances and operating currents. The low start-up

current makes these part ideal for battery applications.

l Small packages: SOT-23, TO-92, SO-8

l Tolerates capacitive loads

l Fixed reverse breakdown voltage of 1.235V

l Tight voltage tolerance ---------- ±0.20%, ±0.5%

l Wide operating current ---------- 15µA to 20mA

l Wide temperature range -------- -40^oC to +85^oC

l Low temperature coefficient --- 100ppm/^oC (max)

l Excellent transient response

Analog Microelectronics offers this part in a TO-92 and

SO-8 packages as well as the space saving SOT-23.

n Applications

l Portable electronics

l Power supplies

l Computer peripherals

l Data acquisition systems

l Battery chargers

l Consumer electronics
