UA305HC vintage adjustable positive voltage regulator (NOS)

The UA305HC is a vintage adjustable positive voltage regulator known for its reliability in legacy applications. Typically housed in a hermetic TO-99 metal can, it delivers a single output voltage adjustable from 1.2 V to 40 V with a maximum output current of 12 mA. It features a maximum dropout voltage of 3.0 V and a power dissipation rating of 500 mW. Originally manufactured by companies such as Fairchild Semiconductor and Fujitsu, this component is now obsolete but remains valuable for maintaining or restoring vintage electronic equipment.
