General Description

The FS8855 is a low-dropout linear regulator that operations in the input voltage range from +2.5V to +9.0V and delivers 500mA output current.

The high-accuracy output voltage is preset at an internally trimmed voltage 2.5V or 3.3V. Other output voltages can be mask-optioned from 1.5V to 5.0V with 100mV increment, except FS8855-29Cx which has 2.85V output voltage.

The FS8855 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 FS8855 devices are available in TO-92, SOT-89 packages.
