The FP6170 is a low dropout, low noise, high PSRR, low quiescent current positive linear regulator. The FP6170 can supply 300mA output current with low dropout voltage at about 160mV that optimized for battery-powered systems or portable wireless devices such as mobile phones. The shutdown function can provide remote control for the external signal to decide the on/off state of FP6170 that consumes less than 0.1μA during shutdown mode.

The FP6170 regulator is able to operate with output capacitors as small as 1μF for stability. The FP6170 fault protection includes the current limit protection and short current protection.

The FP6170 offers high precision output voltage of 1%. The FP6170 is available in UTDFN-4L (1mm×1mm) and SOT-23-5L Packages package which features small size.
