Programmable Shunt Regulator LM431SA, LM431SB, 1. Ref 2. Anode LM431SC 1 3. Cathode
SOT−89 Description CASE 528AH
The LM431SA / LM431SB / LM431SC are three−terminal the 3 output adjustable regulators with thermal stability over operating 1. Cathode temperature range. The output voltage can be set any value between 2. Ref V 3. Anode REF (approximately 2.5 V) and 36 V with two external resistors. 1 2 These devices have a typical dynamic output impedance of 0.2 W.
SOT−23FL
Active output circuit provides a sharp turn−on characteristic, making
CASE 318AB
these devices excellent replacement for zener diodes in many 3 applications. M32 M3 1. Ref 1. Cathode
Features
1 2 2. Cathode 2. Ref • Programmable Output Voltage to 36 V
SOT−23
3. Anode 3. Anode • Low Dynamic Output Impedance: 0.2 W (Typical)
CASE 318BM
• 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
