L7812CV Overview

The L7812CV is a 12 V member of ST's L78 three-terminal positive voltage regulator series in a TO-220 package. It delivers up to 1.5 A with built-in current limiting, thermal shutdown and safe-area protection, so it works as a simple, robust on-card regulator from inputs up to 35 V.

Key Features

  • Fixed 12 V output, 11.5 V to 12.5 V at TJ = 25 °C
  • Output current up to 1.5 A
  • Input voltage up to 35 V
  • Thermal overload, short-circuit and output transition SOA protection
  • Operating junction temperature 0 °C to 125 °C
  • TO-220 through-hole package

Applications

  • Local on-card 12 V regulation
  • Industrial and consumer power supplies
  • Fixed regulators used with external parts for adjustable voltage or current
