GM432 General 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 using two external resistors.
Their active output circuitry provides a very sharp turn-on characteristIc, making them excellent replacements for zener diodes in many applications such as onboard regulation and adjustable power supplies. At home in a wide range of applications, these versatile darlings are ideal voltage references for 3.0V to 3.3V switching power suppies. With operational cathode current as low as 80A, batteries keep on going. Whatever your application, the GM432's offer the optimum combination of performance, reliability, and economy.
