H431AA/BA/CA
AJDUSTABLE SHUNT REGULATOR
Description
H431 series three-terminal adjustable regulators with guaranteed thermal stability over applicable temperature ranges. output voltage value between VREF (approximately TO-92 2.495 volts) volts with external resistors. These devices have typical dynamic output impedance 0.2. Active output circuitry provides very sharp turn-on characteristic, making these devices excellent replacement zener diodes many applications.
