ONSEMI MC7812BDTG Linear Voltage Regulator, Fixed 12V 1A, TO-252

The ONSEMI MC7812BDTG is a monolithic integrated circuit designed as a positive fixed-voltage regulator for a wide variety of applications, including local and on-card regulation. This robust component provides a stable 12V output and can deliver currents in excess of 1A with adequate heat sinking, making it a reliable choice for power supply designs.

Engineered for stability and protection, the regulator features internal current limiting, thermal shutdown, and safe-area compensation for the output transistor. These built-in safeguards protect the device from overload conditions, enhancing the reliability and longevity of your electronic assemblies. Although optimised as a fixed-voltage regulator, it can be used with external components to create adjustable voltage and current supplies, offering design flexibility.
