The FP6733 is a low dropout, low noise, high PSRR, low quiescent current positive linear regulator. The FP6733 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 FP6733 that consumes less than 0.1µA during shutdown mode.
The FP6733 regulator is able to operate with output capacitors as small as 1µF for stability. The FP6733 fault protection includes the current limit protection and current foldback protection.
The FP6733 offers high precision output voltage of 1%.The FP6733 is available in UTDFN-4L (1.0mm×1.0mm) and SOT-23-5 packages which features small size.
