【文字介紹】The FAN25800 is a linear low-dropout regulator with a high PSRR and low output noise. The LDO can provide up to 250mA of output current for 2.8V output and up to 500mA of output current for 3.3V output.
The enable control pin can used to shut down the device and disconnect the output load from the input. During shutdown, the supply current drops below 1uA.
The FAN25800 is designed to be stable with spacesaving ceramic capacitors as small as 0201 case size.TheFAN25800 is available in a 4-bump, 0.35mm pitch, WLCSP package.
