... Ultra−Fast, Low Noise 120 mA CMOS LDO Regulator with Enable The NCP580 series of low dropout regulators are designed for portable battery powered applications which require precise output voltage accuracy, low quiescent current, and high ripple rejection. These devices feature an enable function which lowers current consumption significantly and are offered in the small SC− ...
