The FR9708/A is a low dropout, low noise, high PSRR, low quiescent current positive linear regulator. The FR9708/A 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 FR9708/A that consumes less than 0.1µA during shutdown mode.
The FR9708/A regulator is able to operate with output capacitors as small as 1µF for stability. The FR9708/A fault protection includes the current limit protection and current foldback protection.
The FR9708/A offers high precision output voltage of 1%.The FR9708/A is available in UTDFN-4L (1.0mm×1.0mm) and SOT-23-5 packages which features small size.
