2.5V ADJUSTABLE

SHUNT REGULATOR

Description

Features

The GM431is a three terminal adjustable shunt

regulator with thermal stability guaranteed over

temperature. The output voltage can be adjusted

to any value between 2.5V (V_REF) and 18V by

using two external resistors. The GM431 has a

typical dynamic output impedance of 0.2 . Active

output circuitry provides a very unique turn on

characteristic, making the GM431an excellent

replacement for zener diodes in many

Sink Current Capability 1mA to 100mA

Low dynamic out put impedance, 0.2

typ.

Low output noise

0.5%, 1% or 2% reference voltage

tolerance

Alternate for TL431, LM431 & AS431

Temperature range -40°C to

Available in SOT-23, TO-92, SOT-89 and

Sop- 8 packages

applications such as on board regulation and

adjustable power supplies. The GM431 is an

ideal voltage reference for 3.0 to 3.3V switching

power supplies.

+ 125°C

The GM431 shunt regulator is available with 3

voltage tolerances 0.5%, 1.0% and 2.0% over

full temperature range and four package options

(SOT-23, TO-92, SOT-89 and SO-8).
