Hot-selling and scarce FP6146-18WDGTR 300mA Low Noise High PSRR LDO with Shutdown QFN
FP6146-18WDGTR 300mA Low Noise High PSRR LDO with Shutdown QFN
Product Descriptions
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 percent. 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.
