FP6183
85T
300mA, Low Noise High PSRR
LDO Regulator
Description
The FP6183 is a low dropout, low noise, high PSRR,
very low quiescent current positive linear regulator.
The FP6183 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 FP6183 that
consumes less than 0.1µA during shutdown mode.
The FP6183 regulator is able to operate with output
capacitors as small as 1µF for stability. Other than
the current limit protection, FP6183 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 FP6183 offers high precision output voltage of
2%.The
FP6183 is available in UTDFN – 4L
(1mmx1mm) package which features small size.

Pin Function
The FP6183 is stable with an output capacitor 1µF or greater. The larger output capacitor will be
required for application with larger load transients. The large output capacitor could reduce output
noise, improve stability and PSRR.
Common ground pin.
Pull this pin high to enable IC, pull this pin low to shutdown IC. Floating this pin will be shutdown due to
the built-in pull-low resistor.
Power is supplied to this device from this pin which is required an input filter capacitor. In general, the
input capacitor in the range of 1µF to 10µF is sufficient.
