The FS8853A is a low-dropout linear regulator with ON/OFF control. The device operates in the input voltage range from +2.5V to +9.0V and delivers 300mA output current.
The high-accuracy (±35mV) output voltage is pret at an internally trimmed voltage 2.5V, 2.85V or 3.3V. Other output voltages can be mask-optioned from 1.3V to 5.0V with 100mV increment, except FS8853A-29Cx which has 2.85V output voltage.
The FS8853A consists of a 1.25V reference compare amplifier, a P-channel pass transistor, and an enable/disable logic circuit. Other features include short-circuit protection and thermal shutdown protection. The FS8853 devices are available in SOT-89-5 and SOT-23-5 packages.

Description
GND Ground pin. IN Regulator input pin. NC No Connection. EN Chip enable pin. FS8853A-xxCA FS8853A-xxCB FS8853A-xxCC FS8853A-xxCD FS8853A-xxCE FS8853A-xxCF
OUT Regulator output pin.
IN is the regulator input pin. Supply voltage can range from 2.5V to 9.0V. Bypass with a 1µF capacitor to
GND.
OUT is the output voltage pin. Sources up to 300mA. Bypass with a 3.3µF capacitor to GND.
GND provides the reference for all voltages.
NC no connection.
EN is output voltage ON/OFF control pin. EN pin input voltage must be less than the input voltage at IN
pin.
