可编程并联稳压器 Programmable Shunt Regulator
The LM431A/LM431B/LM431C are three-terminal output adjustable regulators with thermal stability over operating temperature range. The output voltage can be set any value between V
REF
approximately 2.5 volts and 36 volts with two external resistors. These devices have a typical dynamic output impedance of 0.2
W
. Active output circuit provides a sharp turn-on characteristic, making these devices excellent replacement for Zener Diodes in many applications.
