NCP580
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−82AB
package.
