... Circuit Description The NCV4276B is an integrated low dropout regulator that provides a regulated voltage at 400 mA to the output enabled with an input to the inhibit pin. The regulator voltage is provided by a PNP pass transistor controlled by an error amplifier with a bandgap reference, which gives it the lowest possible dropout voltage ...
