01 — About

What it does

The 7805 5V Voltage Regulator IC provides a stable 5V output from higher input voltages up to 35V. It is the standard linear regulator for powering microcontrollers, sensors, and any circuit requiring clean 5V power.

Key features

  • Fixed 5V output
  • Input voltage range 7V-35V
  • 500mA-1A output current (with heatsink)
  • Short-circuit protection
  • Thermal overload protection
  • TO-220 package for heatsink mounting
  • Only 2 external capacitors needed

Good to know

  • Input voltage must be at least 7V (5V + 2V dropout)
  • Heat dissipation = (Vin – 5V) x Iout – use heatsink if >0.5W
  • Add 0.33μF input and 0.1μF output capacitors for stability
  • Tab is connected to GND – can mount directly to chassis
  • For high current, consider switching regulator (more efficient)
  • 78L05 in TO-92 package available for low current (100mA)
