An L7812CV Three-Terminal Positive Voltage Regulator is a fixed 12V linear voltage regulator designed to provide local, on-card power regulation across diverse DC electronic circuits. Encapsulated in a standard TO-220 package with an integrated metal mounting tab, it delivers output currents up to 1.5A when properly heat-sinked. Printed clearly with part number "L7812CV" (STMicroelectronics branding), it features three terminal pins: Input (Pin 1), Ground (Pin 2 / Mounting Tab), and Output (Pin 3), equipped with internal current limiting, thermal overload shutdown, and safe-area protection.

This product is featured by Famephase Electronic Accessories as an essential power management component for 12V system supply rails, operational amplifier dual-rail supplies, audio preamplifiers, relay control circuits, and automotive electronics conditioning.
