General Description

The FS8853 is a low-dropout linear regulator that operations in the input voltage range from +2.5V to +9.0V and delivers 300mA output current.

The high-accuracy output voltage is preset at an internally trimmed voltage 1.8V to 3.3V. Other output voltages can be mask-optioned from 1.5V to 5.0V with 100mV increment.

The FS8853 consists of a 1.25V bandgap reference, an error amplifier, and a P-channel pass transistor. Other features include short-circuit protection and thermal shutdown protection. The FS8853 devices are available in SOT-89 and SOT-23 packages.
