An L7912CV Three-Terminal Negative Voltage Regulator is a fixed -12V linear voltage regulator designed to supply stable negative voltage rails in dual-supply analog circuits. Encapsulated in a standard TO-220 package with a metallic heatsink tab, it can deliver output currents exceeding 1.5A when properly heat-sinked. Printed clearly with part number "L7912CV" (STMicroelectronics branding), it features three terminal pins: Ground (Pin 1), Input (Pin 2 / Mounting Tab), and Output (Pin 3), integrated with internal current limiting, thermal overload protection, and safe-area compensation.

This product is featured by Famephase Electronic Accessories as an essential power management component for dual-rail op-amp power supplies (working alongside L7812CV for 12V rails, audio preamplifiers, analog-to-digital interface cards, and instrumentation circuits.
