7812 Voltage Regulator

The 7812 voltage regulator is a commonly used linear voltage regulator that provides a fixed +12V DC output from a higher voltage DC input. It's part of the 78xx series of regulators, where "xx" denotes the output voltage.

Key Specs of the 7812:

• Output voltage: +12V
• Input voltage range: Typically needs at least 14V input to regulate properly (due to dropout voltage)
• Maximum output current: Around 1A (can go up to 1.5A with proper heat sinking)
• Dropout voltage: ~2V (so input should be 14V or higher)
• Internal current limiting, thermal shutdown, and short circuit protection

Basic Pinout (TO-220 package):

1. Input – connect your unregulated DC voltage
2. Ground – common ground
3. Output – regulated +12V output
