Today, more and more devices are shrinking or becoming wearable. As devices shrink, so do their components. Low-dropout regulators (LDO regulators) such as the NCP170 series and the NCP171 are perfect for regulating voltage in smaller devices. The NCP 170 series of CMOS LDO regulators are designed specifically for battery-powered applications which require ultra-low quiescent current. The NCP171 is a dual-mode LDO regulator offering up to 80mA in active mode and as low as 50nA of Iq in low power mode, allowing devices to become more efficient.
 
NCP170

The NCP170 series of CMPS low dropout regulators are designed specifically for portable battery-powered applications which require ultra-low quiescent current. This series ensures improved battery life and low power dissipation at full load. The small package sizes also make the NCP170 series suitable for application in devices with space constraints.
