Fixed 5V output, 1A, TO-220 package
| Output | 5V fixed |
|---|---|
| Dropout | 2V |
| Package | TO-220 |
| Input Range | 7-35V |
| Max Current | 1A |
The LM7805 is the simplest way to get a stable 5V output from a 7–35V input. No PWM switching noise, no inductor required — just a capacitor on each side and you have a clean 5V linear regulated supply. Industry-standard TO-220 package, 1A max current.
The LM7805 dissipates the voltage difference as heat. At 12V input / 5V output / 500mA, it dissipates 3.5W — requiring a heatsink. For battery-powered applications, use a LM2596 buck converter instead for 92% efficiency. The LM7805 excels in low-noise applications (audio, precision sensors) where switching converter noise is unacceptable.
