The FAN1117A and FAN1117A-5 integrated circuits from Fairchild consist of fixed and adjustable regulators for currents up to 1 A. The FAN1117A-5 is a fixed regulator for a 5 V output voltage and is supplied in TO-220, SOT-223 housing And TO-252 three-terminal. The FAN1117A can have its output voltage adjusted for 9 V voltages or other values through a resistive divider, as shown in the figure. The voltages can be 1.8 V, 2.5 V, 2.85 V, 3.3 V, 5 V up to 9 V. The typical setting is 0.05% (load) and the device has a low drop Of driving tension. The thermal current limitation is on-chip.
