This document is a technical schematic for a +5V voltage regulator circuit designed by the Digital Equipment Corporation in 1969. The circuit utilizes a dual-transistor configuration (2N4398) for power regulation and includes various resistors, capacitors, and diodes (such as the D664 and SDA-7) to manage voltage output. The schematic includes specifications for component tolerances, connector housings (P1 and P2), and a transistor and diode conversion chart to assist with maintenance and testing.
