L7812AC PDF Datasheet – 1.5A, 12V, Voltage Regulator

A voltage regulator is an electronic circuit that maintains a constant voltage level. It is designed to provide a stable output voltage that is independent of the changes in input voltage, load current, temperature, and other environmental conditions.

Voltage regulators are used in a variety of applications, including power supplies for electronic devices, battery charging systems, and voltage stabilizationization for sensitive equipment. They help protect the devices from damage due to voltage fluctuations or overloading, and ensure that the devices receive a consistent, reliable power source.

There are several types of voltage regulators, including linear regulators, switching regulators, and voltage stabilizing circuits.

Description

This is 12v, Positive voltage regulator. The L7812AC series of three-terminal positive regulators is available in TO-220, TO-220FP, D²PAK and DPAK 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 embeds internal current limiting, thermal shutdown and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with […]
