GM432
GM432 is 1.24V ADJUSTABLE PRECISION SHUNT REGULATORS manufactured by Gamma Microelectronics.
Description
The GM432's are low-voltage three-terminal adjustable precision shunt regulators with specified thermal stability over their full temperature range. Output voltage can be set to any value from Vref (1.24V) to 16V by using two external resistors. Their active output circuitry provides a very unique turn-on characteristic, making them excellent replacements for zener diodes in many applications such as onboard regulation and adjustable power supplies. In a wide range of home applications, these versatile darlings are ideal voltage references for 3.0V to 3.3V switching power suppies. With operational cathode current as low as 80µA, batteries keep on going. Whatever your application is, the GM432's offer the optimum bination of performance, reliability, and economy.
Features
Low-voltage operation, down to 1.24V 0.5%, 1% or 2% reference voltage tolerance Adjustable output voltage, VO = Vref to 16V Sink Current Capability 80µA to 100m A Low dynamic output impedance, 0.05W typical Wide temperature range, 0° to +70°C Pin-to-pin replacement for TLV431, SC431L Available in SOT-23, SOT-25, SOT-89, TO-92 and SOP-8
Application
Switching power supplies Linear regulators Adjustable supplies Instrumentation Battery-operated puters, PDA's portable devices Monitors, TV's, camcorders puter disk drives
