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.
