... NCP566 1.5 A Low Dropout Linear Regulator The NCP566 low dropout linear regulator will provide 1 fixed output voltage. The fast loop response and low dropout voltage make this regulator ideal for applications where low voltage and good load transient response are important. Device protection includes current limit, short circuit protection, and thermal shutdown ...

... The discharge current depends on the value of the capacitor, the output voltage and the rate at which V NCP566 linear regulator, the discharge path is through a large junction and protection diodes are not usually needed. If the regulator is used with large values of output capacitance and the input voltage is instantaneously shorted to ground, damage can occur ...
