LM431SA

DATA SHEET www.onsemi.com 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 ORDERING INFORMATION 1 SOT−89 CASE 528AH 3 12 SOT−23FL CASE 318AB 3 12 SOT−23 CASE 318BM 1.
