LM431SA, LM431SB,
LM431SC
Programmable Shunt
Regulator
Description
The LM431SA / LM431SB / LM431SC are three−terminal the
output adjustable regulators with thermal stability over operating
temperature range. The output voltage can be set any value between
VREF (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 replacement 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)
• Temperature Compensated for Operation Over Full Rated Operating
Temperature Range
• Low Output Noise Voltage
• Fast Turn−on Response
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
