When a regulated power supply incorporating a series pass transistor as the regulating element is crow-barred, the control circuitry continues to drive the pass transistor to maximum available current. The pass transistor may be overheated and eventually both the pass transistor and the crow-bar itself may be damaged. To prevent this latter from happening, the drive to the pass transistor is cut back in response to the actuation of the crow-bar.
