WebJul 6, 2024 · Here is the 7805 datasheet which is the popular 5V voltage regulator IC and the 7805 pinout. It is designed to provide a constant 5V at 1.5A max when powered by 7.3V to 35V. We usually use it as a stable voltage source for a common digital circuit. Sometimes, the power supply using a transformer can have too high a voltage. WebIn this example the RED chip LED has a Vf of 2 volts. You could power it from a 3.3 volt supply. You could gang together two, cathode to anode, and run them from a 5 volt supply. ( as shown below) The Vf value is key to calculating the correct current limiting resistor in a future step. Stay tuned! Forward Current rating
