NCP4681, NCP4684

150 mA, Ultra Low

Quiescent Current, Low

Dropout Regulator

The NCP4681 and NCP4684 are CMOS Linear voltage regulators

with 150 mA output current capability and ultra low supply currents

(1 mA typ.) The devices are easy to use and include output current

protection and a fully integrated soft−start circuit to minimize inrush

current and to ensure no output voltage overshoot. The NCP4681

includes an Enable function to reduce supply current by using a

Standby mode, while the NCP4684 excludes the Enable pin to avoid

any pull down current, thereby offering the lowest possible current

consumption for battery powered applications in Active mode. For

portable products the devices are available in the exceptionally small

0.8 x 0.8 mm XDFN, along with the SC−70 and SOT23 packages
