GM431

2.5V ADJUSTABLE SHUNT REGULATOR

Features

Description

The GM431 is a three terminal adjustable shunt regulator

with thermal stability guaranteed over temperature. Output

voltage can be adjusted to any value between 2.5V (V

Sink Current Capability 1 mA to 100mA

Low dynamic output impedance, 0.2W typ.

Low output noise

)

ref

and 36V by using two external resistors. The GM431 has a

0.5%, 1% or 2% reference voltage tolerance

Alternate for TL431, TL431, LM431 & AS431

Temperature range 0°C to+ 70 °C

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

SOP- 8 packages

typical dynamic output impedance of 0.2W. Active output

circuitry provides a very unique turn on characteristic, mak-

ing the GM431 an excellent replacement for zener diodes

in many applications such as onboard regulation and ad-

justable power supplies. The GM431 is an ideal voltage ref-

erence for 3.0 to 3.3V switching power supplies.

The GM431 shunt regulator is available with 3 voltage tol-

erances 0.5%, 1.0% and 2.0% over T = 0°C to + 70°C,

and four package options (SOT-23, TO-92, SOT-89 and

SOP-8). Whatever your application is, the GM431 offers

the optimum combination of performance, reliability, and

economy.
