FAN431ZXA

可编程并联稳压器 Programmable Shunt Regulator

Description

The FAN431/FAN431A/FAN431L are three terminal output adjustable regulators with thermal stability over operating temperature range. The output voltage can be set any value between VREF approximately 2.5 volts and 36 volts with two external resistors. These devices have a typical dynamic output impedance of 0.2Ω. Active output circuit provides a sharp turn-on characteristic, making these devices excellent replacement for Zener Diodes in many applications.

Features
