NCP582/D
NCP582
Ultra−Fast, Low Noise
150 mA CMOS LDO
Regulator with Enable
The NCP582 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 and are offered in active
low and active high with auto discharge.
The following ceramic capacitors are the recommended values to
be used with these devices; for V
