GM431
GM431 is 2.5V ADJUSTABLE SHUNT REGULATOR manufactured by Gamma Microelectronics.
Features
Sink Current Capability 1 m A to 100m A Low dynamic output impedance, 0.2W typ. Low output noise 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
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 (Vref) and 36V by using two external resistors. The GM431 has a typical dynamic output impedance of 0.2W. Active output circuitry provides a very unique 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= 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 bination of performance, reliability, and economy.
