2 GND Power supply ground.

3 CE Chip enable pin.

Overview

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.

A 2.2 mF ceramic capacitor or higher is the recommended value to be used with these devices on the output pin.
