Programmable Shunt

Regulator

LM431A, LM431B, LM431C

Description

The LM431A/LM431B/LM431C are three−terminal output

adjustable regulators with thermal stability over the full operating

temperature range. The output voltage can be set to any value between

REF

(approximately 2.5 V) and 36 V 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 replacements for Zener diodes in many

applications.

Features

• Programmable Output Voltage to 36 V

• Low Dynamic Output Impedance: 0.2 W (Typical)

• Sink Current Capability: 1.0 to 100 mA

• Equivalent Full−Range Temperature Coefficient of 50 ppm/°C

(Typical)

TO−92

CASE 135AN
