Description

The GM432s 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 GM432s offer the optimum combination of performance, reliability, and economy.
