Description

The GM431 is a three terminal adjustable shunt regulator with thermal stability guaranteed over temperature. Output
voltage can be adjusted to any value from 2.5V (Vref) to 36V using two external resistors. The GM431 has a typical dynamic output impedance of 0.2W. Active output circuitry provides a very sharp turn on characteristic, making the GM431 an excellent replacement for zener diodes in many applications such as onboard regulation and adjustable power supplies. The GM431 is an ideal voltage reference for 3.0 to 3.3V switching power supplies.

The GM431 shunt regulator is available with 3 voltage tolerances 0.5%, 1.0% and 2.0% over TA= -40°C to + 85°C, and four package options (SOT-23, TO-92, SOT-89 and SOP-8). Whatever your application, the GM431 offers the optimum combination of performance, reliability and economy.
