## Description

The classic L7805 linear voltage regulator in a TO-220 package, capable of delivering a clean, regulated 5.0 V output (±2%) from an input voltage of 7–35 V. With built-in current limiting and thermal shutdown protection, it's a robust and forgiving choice for powering just about any 5 V electronics project. As a linear regulator, excess voltage is dissipated as heat. The dropout voltage is approximately 2 V, so a minimum input of 7 V is required for a stable 5 V output. Higher input voltages and currents produce more heat — a heatsink is recommended for sustained loads above a few hundred milliamps. Key Features 5.0 V Regulated Output – ±2% regulation accuracy Up to 1.5 A Output – With appropriate heatsinking Wide Input Range – 7–35 V DC Built-In Protection – Internal current limiting and thermal shutdown TO-220 Package – Easy to heatsink and mount Specifications Output Voltage – 5.0 V Maximum Output Current – 1.5 A Input Voltage Range – 7–35 V Dropout Voltage – ~2 V Quiescent Current – 6 mA Package – TO-220 Junction Thermal Resistance – 62.5°C/W (without heatsink can dissipate ~2 W) Ideal For Powering 5 V circuits from battery packs or wall adapters Arduino and microcontroller power supplies Breadboard and prototyping power rails Any project needing a simple, reliable 5 V source Note: While capacitors are not strictly required for stability, adding 10 µF electrolytic capacitors on both the input and output is recommended for best performance. Heat dissipation = (Vin − 5 V) × Iout — for example, a 9 V input at 1 A produces 4 W of heat and requires a heatsink.
