FS8854
350mA LDO Linear Regulator
General Description
The FS8854 is a low-dropout linear regulator that operations in the input voltage range from +2.5V to +6.5V and delivers 350mA 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, except FS8854-29Cx which has 2.85V output voltage. The FS8854 consist 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 FS8854 devices are available in TO-92, SOT-89 and SOT-23 packages.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and function operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
