FS8853 300mA LDO Linear Regulator General Description Ordering Information General Description Ordering Information FS8853-xx x x The FS8853 is a low-dropout linear regulator that operations in the input voltage range from +2.5V Package Pin Out to +9.0V and delivers 300mA output current. The high-accuracy output voltage is preset at an A : SOT-23 1.IN 2.GND 3.OUT internally trimmed voltage 2.5V or 3.3V. Other B : SOT-23 1.GND 2.IN 3.OUT C : SOT-23 1.GND 2.OUT 3.IN output voltages can be mask-optioned from 1.3V V : SOT-23 1.OUT 2.GND 3.IN to 4.5V with 100mV increment, except D : TO-92 1.IN 2.GND 3.OUT FS8853-29Cx which has 2.85V output voltage. E : TO-92 1.GND 2.IN 3.OUT The FS8853 consists of a 1.25V bandgap F : TO-92 1.OUT 2.GND 3.IN W : TO-92
