300mA LowLDNOoisweithHSighhutPdSo8Rw5RnT
Description
The FP6146 is a low dropout, low noise, high PSRR,
very low quiescent current positive linear regulator.
The FP6146 can supply 200mA output current with
low dropout voltage at about 300mV 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 FP6146 that
consumes less than 0.1µA during shutdown mode.
The FP6146 regulator is able to operate with output
capacitors as small as 1µF for stability. Other than
the current limit protection, FP6146 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 FP6146 offers high precision output voltage of
2%. It is housed in low-profile, space-saving
SOT-23-3, SOT-23-5, TSOT-23-5, TDFN-6
(1.6mm×1.6mm), SC-82-4 and SC-70-5 packages.

Pin Function
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.
The output supplies power to loads. The output capacitor is required to prevent output voltage from oscillation.
The FP6146 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.
No connection
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.
