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 2.5V or 3.3V. Other output voltages can be mask-optioned from 1.3V to 4.5V with 100mV increment, except FS8853-29Cx which has 2.85V output voltage. 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 TO-92, SOT-89 and SOT-23 packages. Features Low dropout voltage 400mV at 300mA (Typ.) Up to ±35mV output voltage accuracy (VIN≦ 7V) Preset at 2.5V, 3.3V Mask options from 1.3V to 4.5V Small output capacitor Output current limit Thermal overload shutdown protection TO-92, SOT-89 and SOT-23 Package Applications Battery Powered Equipment Palmtops Portable Cameras and Video Recorders Reference Voltage Sources Post Regulator for Switching Power
