Voltage Regulator (3-pin)
Schematic symbol
Gives a fixed, steady output voltage from a higher input, like the 7805 that makes 5 V. The input must be at least about 2 V above the output, and the extra voltage turns into heat, so it may need a heatsink at higher currents. Add capacitors on the input and output (e.g. 0.33 µF and 0.1 µF). The 79xx versions are for negative voltages and have a different pinout. Learn more about voltage regulators
