The FAN25800 is a linear low-dropout regulator with a high PSRR (85 dB at 100 Hz) and low output noise (typically 8 µVRMS over a 10 Hz to 100 kHz bandwidth). The LDO can provide up to 250 mA of output current for 2.8 V output and up to 500 mA of output current for 3.3 V 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 1 µA.
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, 0.35 mm pitch, WLCSP package.
