LM431A / LM431B / LM431C — Programmable Shunt Regulator
June 2013
LM431A / LM431B / LM431C
Programmable Shunt Regulator
Features
Programmable Output Voltage to 36 V
Low Dynamic Output Impedance: 0.2
Ω
(Typical)
Sink Current Capability: 1.0 to 100 mA
Equivalent Full-Range Temperature Coefficient of
50 ppm/°C (Typical)
• Temperature Compensated for Operation Over Full
Rated Operating Temperature Range
• Low Output Noise Voltage
• Fast Turn-on Response
Description
The LM431A / LM431B / LM431C are three-terminal out-
put adjustable regulators with thermal stability over the
full operating temperature range. The output voltage can
be set to any value between V
REF
(approximately 2.5 V)
and 36 V with two external resistors. These devices have
a typical dynamic output impedance of 0.2
Ω.
Active out-
put circuit provides a sharp turn-on characteristic, mak-
ing these devices excellent replacements for Zener
diodes in many applications.
