L432 General Description
The L432 is a three-terminal adjustable shunt regulator utilizing an accurate 1.24V band gap reference. The output voltage can be set to any value between 1.24V (VREF ) to 18V with two external resistors as shown in the typical application circuit. The device exhibit a wide operating current range of 0.2 to 100 mA with a typical dynamic impedance of 0.25. Active output circuitry provides a very sharp turn-on characteristic, making the L432 excellent re- pla cements for low-voltage zener diodes in many applications, including on-board regulat- ion and adjustable power supplies.
When used with an opto-coupler, the L432 is ideal voltage reference in isolated feedback circuits for 3.3V switching-mode power supplies. The L432 shunt regulator is available in two voltage tolerances (0.5% & 1.0%) and three package options (TO-92, SOT-23-3 and SO-8).
