L7812CV Linear Voltage Regulator, +12V, 1.5A, TO-220

Description

L7812CV Linear Voltage Regulator (+12V, 1.5A, TO-220)
The L7812CV is a three-terminal positive linear voltage regulator designed to provide a fixed, stable 12.0V DC output. Housed in an industry-standard TO-220 package, this monolithic integrated circuit features built-in current limiting, safe-area protection, and internal thermal shutdown, making it a highly reliable and durable choice for local on-card regulation.

* Component Type: Monolithic Positive Linear Voltage Regulator
* Output Voltage: Fixed +12.0 Volts DC (typically within a ±4% output voltage tolerance)
* Maximum Output Current: 1.5 Amps (with adequate heat sinking)
* Input Voltage Range: Minimum 14.5 Volts DC up to a maximum of 35 Volts DC
* Dropout Voltage: Typically 2.0 Volts (the minimum voltage overhead required between input and output to maintain regulation)
* Package Style: TO-220 (through-hole plastic casing with a built-in metal tab for mounting an external heat sink)
* Built-In Protection Features: Internal thermal overload protection, internal short-circuit current limiting, and output transistor safe-area compensation
* Applications: Widely used in linear power supplies, audio amplifier power rails, automotive electronics steps, hobbyist breadboard power supplies, and logic system sub-regulation circuits
