FP6146
300mA Low Noise High PSRR
LDO with Shutdown
Description
Features
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.
Low Dropout Voltage of 300mV at 200mA
Low 30μVrms Output Noise
Guaranteed 300mA Output Current
High Power Supply Rejection Ratio of 70dB at
10kHz
Very Low Quiescent Current at 35µA
Max. 2% Output Voltage Accuracy
Needs Only 1µF Capacitor for Stability
Fast Response in Line/Load Transient
Thermal Shutdown Protection
Current Limit Protection
Low-ESR Ceramic Capacitor for Output Stability
Miniature Packages:
SOT-23-3, SOT-23-5, TSOT-23-5, TDFN-6
(1.6mm×1.6mm), SC-82-4 and SC-70-5
RoHS Compliant
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
