fitipower integrated technology lnc. FP6166 600mA LowLDNOoisweithHSighhutPdSo8Rw5RnT Description The FP6166 is a low dropout, low noise, high PSRR and very low quiescent current positive linear regulator. The FP6166 can supply 600mA output current with low dropout voltage at about 890mV 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 FP6166 that consumes less than 0.1µA during shutdown mode. The FP6166 regulator is able to operate with output capacitors as small as 1µF for stability. Other than the current limit protection, FP6166 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 FP6166 offers high precision output voltage of 2%. It is housed in low-profile, space-saving SOT-23-5 and SOP-8 packages.

Typical Application Circuit of FP6166 Note 1:To prevent oscillation, it is recommended to use minimum 2.2µF/1µF X7R or X5R dielectric capacitors if ceramics are used as input/output capacitors. Functional Pin Description Pin Name VIN VOUT ADJ 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 2.2µ F to 10µ F is sufficient. The output supplies power to loads. The output capacitor is required to prevent output voltage from oscillation. The FP6166 is stable with a 1µ F or greater output capacitor. 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. Voltage Feedback Input Pin. Connect ADJ and VOUT with a resistive voltage divider. GND Common Ground Pin Pull this pin high to enable IC, and pull this pin low to shutdown IC. Keeping this pin floating will shut down IC due to the built-in pull-low resistor.
