FP6185 85T 300mA, Low Noise High PSRR LDO Regulator Description Features The FP6185 is a low dropout, low noise, high PSRR, very low quiescent current positive linear regulator. The FP6185 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 FP6185 that consumes less than 0.1µA during shutdown mode. The FP6185 regulator is able to operate with output capacitors as small as 1µF for stability. Other than the current limit protection, FP6185 also offers the on chip thermal shutdown feature providing protection against overload or any condition when the ambient temperature exceeds the maximum junction temperature.              Low VIN and Wide VIN Range: 2V to 5.5V Guarantee Output Current 300mA 2% Output Voltage Accuracy Output Noise 65μVrms from 10Hz to 100kHz VOUT Fixed 1.1V to 3.3V Low Dropout Voltage of 400mV at 300mA Ripple Rejection 70dB at 10kHz Very Low Quiescent Current at 35µA Needs Only 1µF Capacitor for Stability Thermal Shutdown Protection Current Limit Protection Miniature Packages: SOT-23-5, UTDFN-4L (1mm×1mm) RoHS Compliant Applications The FP6185 offers high precision output voltage of 2%.The FP6185 is available in SOT-23-5 and UTDFN – 4L (1mmx1mm) packages which features small size.   Pin Assignment Ordering Information   PDAs, Mobile phones, GPS, Smartphones Wireless Handsets, Wireless LAN, Bluetooth® , Zigbee® Portable Medical Equipment Other Battery Powered Applications FP6185-□□ S5 Package (SOT-23-5) VOUT Package Type S5: SOT-23-5 X6: UTDFN-4L NC 5 4 (Marking) 1 2 3 Output Voltage VIN GND SHDN X6 Package (UTDFN-4L)(1mmx1mm) (Top view) VIN SHDN 3 4 UTDFN-4L Marking Part Number Product Code FP6185- EP 1 VOUT 2 GND Figure 1.

In general, the input capacitor in the range of 1µ F to 10µ F is sufficient. The FP6185 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.

Current limit and on chip thermal shutdown features provide protection against any combination of overload or ambient temperature that could exceed maximum junction temperature. 1. Output and Input Capacitor The FP6185 regulator is designed to be stable with a wide range of output capacitors. The ESR of the output capacitor affects stability. Larger value of the output capacitor decreases the peak deviations and improves transient response for larger current changes. The capacitor types (aluminum, ceramic, and tantalum) have different characterizations such as temperature and voltage coefficients. All ceramic capacitors are manufactured with a variety of dielectrics, each with different behavior across temperature and applications. Common dielectrics used are X5R, X7R and Y5V. It is recommended to use 1µF to 10µF X5R or X7R dielectric ceramic capacitors with 30m to 50m ESR range between device outputs and ground for stability. The FP6185 is designed to be stable with low ESR ceramic capacitors and higher values of capacitors and ESR could improve output stability. The ESR of output capacitor is very important because it generates a zero to provide phase lead for loop stability. 2. Protection Features In order to prevent overloading or thermal condition from damaging the device, FP6185 has internal thermal and current limiting functions designed to protect the device. It will rapidly shut off PMOS pass element during over-temperature condition. 3. Thermal Consideration The power handling capability of the device will be limited by allowable operation junction temperature (125ºC). The power dissipated by the device will be estimated by PD=IOUT(VIN-VOUT). The power dissipation should be lower than the maximum power dissipation listed in “Absolute Maximum Ratings” section. 4. Shutdown Operation The FP6185 is shutdown by pulling the input low, and turned on by driving the high. If pin floating, the FP6185 will shut down because pin has built-in a pull low resistor (refer to Block Diagram). There are no requirements for the ESR on the input capacitor, but its voltage and temperature coefficient have to be considered for device application environment.
