G822 -6V Regulator

Summary The G822 module is a voltage regulator designed for the PDP-15 memory system. It features an integrated over-voltage protection circuit and a sensing circuit that issues a "power OK" signal if the output exceeds -6.5V.

Key operational characteristics include:

• Input: Operates on 11V power provided by the 715 power supply.
• Outputs:
  • A primary variable output ranging from -5.0V to -7.0V at 1.5A.
  • A secondary variable threshold voltage output (0 to -6.0V) used for the G100 module.
  • A TTL-compatible signal (BN1) that drops to ground when the output voltage becomes more negative than -6.5V.
