SS432G Datasheet | Silicon

FEATURES Low voltage operation (1.24V) Adjustable output voltage from VO = V REF to 12V Wide operating current range from 55µ A to 100m A Low dynamic output impedance 0.25Ω typ. ESD rating is 6k V (per MIL-STD 883D) DESCRIPTION The SS432G is a low-voltage three-terminal adjustable shunt regulator with a guaranteed thermal stability over the applicable temperature range. The output voltage can be set to any value between VREF (approximately 1.24V) to 12V with two external resistors (see application circuit). This device has a typical output impedance of 0.25 ohms. Active output circuitry provides very sharp turn-on characteristics, making this device an excellent replacement for Zener diodes in many applications. The SS432G is characterized for operation from 0°C to 105°C, and three package options (SOT-23, SOT-89, and TO-92) allow the designer the opportunity to select the proper package for his application.
