Voltage Regulator 7812CV 12V 1.5A

The Voltage Regulator 7812CV is a fixed positive linear regulator that delivers a steady 12 V output at up to 1.5 A from a higher DC input. It comes in a TO-220 package that is easy to mount on a heatsink, and it has built-in thermal overload and short-circuit protection, making it a simple, reliable way to get 12 V for relays, fans and analog circuits.

Voltage Regulator 7812CV Specifications

• Output voltage: 12 V fixed
• Output current: up to 1.5 A (with a suitable heatsink)
• Input voltage: at least about 14.5 V, 35 V maximum
• Protection: thermal overload, short-circuit current limiting, safe-area protection
• Package: TO-220, pins IN, GND, OUT (tab connected to GND)

Voltage Regulator 7812CV Applications

• 12 V supplies for relays, fans and small LED strips
• Regulating a rectified transformer or 18–24 V adapter output down to 12 V
• Powering op-amp and audio circuits
• Electronics labs and power supply projects

What's in the Box

• 1 × 7812CV 12 V voltage regulator

Tip: Fit a 0.33 µF capacitor at the input and a 0.1 µF capacitor at the output, close to the pins. The regulator dissipates (Vin − 12 V) × current as heat, so use a heatsink when the current or input voltage is high.
