Adjustable shunt regulator
PL432XA3/N3
Features
◆Low voltage operation(down to 1.24V) ◆Wide operating current range 80μA to 100mA ◆Low dynamic output impedance 0.05Ω typ. ◆Trimmed bandgap design ±0.25% ◆Upgrade for PL431 ◆Available in TO-92 and SOT-23 packages The PL432 is a three terminal adjustable shunt regulator with thermal stability guaranteed over temperature. The output voltage can be adjusted to any value from 1.24V(VREF) to 20V with two external resistors. The PL432 has a typical dynamic output impedance of 0.05Ω. Active output circuitry provides a very sharp turn on characteristic, making the PL432 an excellent replacement for zener diodes.
