ABSTRACT:
An improved optically controlled power supply regulator in which an optoisolator transistor is controlled by an input light emitting diode replaces an optically controlled power supply regulator with a light emitting diode controlled with a light dependent resistor. The optically controlled power supply regulator utilizes a capacitor and a resistor to reduce loop response oscillation in order to prevent the optically controlled power supply regulator from being shut down on a system board.
