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.
