GM431BST23R中文资料GAMMA数据手册PDF规格书

描述 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.
