Fairchild FAN25800 LDO Voltage Regulators

Fairchild FAN25800 LDO Voltage Regulators

Fairchild's FAN25800 LDO voltage regulators offers a high PSRR (85dB at 100Hz) and low output noise (typically 14.1μVRMS over a 10Hz to 100kHz bandwidth). This LDO voltage regulator can provide up to 250mA of output current for 5.14V output and up to 500mA of output current for 3.3V output. The enable control pin can be used to shut down the device and disconnect the output load from the input. During shutdown, the supply current drops below 1μA. The FAN25800 is designed to be stable with space-saving ceramic capacitors as small as 0201 case size. The FAN25800 is available in a 4-bump, 0.35mm pitch, WLCSP package.
