The AHK432 is a low voltage adjustable shunt referencewith thermal stability guaranteed over the full industrialtemperature range. This three-terminal regulator has anoutput voltage range that extends from VREF (1.24V) to20V, giving designers outstanding flexibility in the developmentof power supplies and instrumentation. With alow operating current of 60μA, the AHK432 is well suitedfor battery-powered portable electronic applications. Italso has a sharp turn-on characteristic and a dynamicresistance of only 50mΩ, making it an excellent replacementfor zener diodes in low tempco designs.
