Voltage Regulator 5V
Convert 9 volts to a constant 5 volts.
Components:
- 100uF Polarized Capacitor
- .1uF Ceramic Capacitor
- Switch (On/Off)
- LM7805L Voltage Regulator
- 9 Volts battery
This circuit works with inputs higher and lower than 9 volts also, but not lower than 5 volts. See the datasheet for the LM7805 to know more.
