L7812CV Datasheet PDF – 1.5A, 12V, Voltage Regulator – ST

Part Number: L7812CV

Function: 1.5A, 12V, Positive Voltage Regulator

Package: TO-220 Type

Manufacturer: STMicroelectronics





The L7812CV is 1.5A, 12V, Voltage Regulator.

The L7800 series of three-terminal positive regulators is available in TO-220, TO-220FP, TO-3 and D2PAK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.

A voltage regulator is an electronic device that is used to maintain a constant voltage level, regardless of changes in load or input voltage. It does this by adjusting the output voltage so that it remains within a specified range. Voltage regulators can be found in a variety of electronic devices, including power supplies, batteries, and automotive systems. They are essential components in many electronic systems to ensure reliable and safe operation.
