The FS8856 is a low-dropout linear regulator from Fortune Semiconductor Co. It operates in the input voltage range from +2.5V to +6.5V and delivers 550mA 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 1.3V to 5.0V with 100mV increment. The FS8856 consists of a 1.25V reference compare amplifier, and a P-channel pass transistor. Other features include short-circuit protection and thermal shutdown protection. The FS8856 devices are available in TO-92, SOT-89 and SOT-223 packages.
