AT432 Datasheet | IAT

FEATURES Immense Advance Tech. DESCRIPTION Low voltage operation (down to 1.24V) Wide operating current range 80µA to 100m A 0.2Ω Typical output impedance Voltage reference tolerance 1％ for B series and 0.5％ for A series Pin-to-Pin replacement for TLV431 and SC431L Available in SOT-23, SOT-25(SOT-23-5),SOT-89 and TO-92 packages APPLICATION Linear Regulators Adjustable Supplies Switching Power Supplies Battery Operated puters Instrumentation puter Disk Drives The AT432 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 18V with two external resistors. The AT432 has a typical dynamic output impedance of 0.2Ω. Active output circuitry provides a very sharp turn on characteristic, making the AT432 an excellent replacement for zener diodes. When bined with an optocoupler, the AT432 can be used as an...
