Part Number LM431A
Description Programmable Shunt Regulator
Feature Programmable Shunt Regulator LM431A, LM4 31B, LM431C Description The LM431A/LM43 1B/LM431C are threeβˆ’terminal output a djustable regulators with thermal stabi lity over the full operating temperatur e range.
The output voltage can be set to any value between VREF (approximatel y 2.
5 V) and 36 V with two external res istors.
These devices have a typical dy namic output impedance of 0.
2 W.
Active output circuit provides a sharp turn∠’on characteristic, making these device s excellent replacements for Zener diod es in many applications.
