G822 -6V Regulator

The G822 module is designed for the PDP-15 computer system, providing a regulated -6V output with integrated over-voltage protection and a sensing circuit to generate a "memory power OK" signal.

Key Specifications:

• Input: Operates on 11V power from the 715 power supply.
• Output A: Variable -5.0V to -7.0V at 1.5A.
• Output B: Variable 0V to -6.0V threshold voltage for the G100 module (nominally -3.8V).
• Output C (BN1): TTL signal that drops to ground if the -6V output exceeds -6.5V.
