... Circuit Description The NCV8665 is an integrated low dropout regulator that provides 5.0 V, 150 mA protected output and a signal for power on reset. The regulation is provided by a PNP pass transistor controlled by an error amplifier with a bandgap reference, which gives it the lowest possible drop out voltage and best possible temperature stability. The output ...
