FP6185-33S5

The FP6185 is a low dropout, low noise, high PSRR, very low quiescent current positive linear regulator. The FP6185 can supply 300mA output current with low dropout voltage at about 400mV 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 FP6185 that consumes less than 0.1μA during shutdown mode. The FP6185 regulator is able to operate with output capacitors as small as 1μF for stability. Other than the current limit protection, FP6185 also offers the on chip thermal shutdown feature providing protection against overload or any condition when the ambient temperature exceeds the maximum junction temperature. The FP6185 offers high precision output voltage of ±2%. The FP6185 is available in SOT-23-5 and UTDFN – 4L (1mmx1mm) packages which features small size.
