Programmable Shunt
Regulator
LM431SA, LM431SB, LM431SC
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
