Abstract : A Schottky diode, whose forward voltage is 0.4 volts is connected between the load and one input of the sense amplifier, which has a minimum operating voltage of 0.6 volts. When the load becomes short circuited or drops to a very low resistance, the Schottky diode conducts to shut down the sense amplifier, which cuts off the series pass transistor. When the load resistance rises to a predetermined value, the Schottky diode becomes reverse biased, permitting the regulator to return to its normal regulation operation. (Author)
