- Short-circuit current limiting  
- Internal overheat protection  
- Low cost and easy to use  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

3 Terminal 1A Positive Voltage Regulator

Alternative Part Number

  • L7812CD2T-TR --: 12V positive linear voltage regulator in D2PAK, same function and package style as the original, widely available and pin-compatible.
  • MC7812BD2TG --: 12V fixed linear regulator in D2PAK with similar current rating and thermal performance, a common drop-in replacement.
  • LM7812SX/NOPB --: 12V fixed regulator in TO-263 (D2PAK) package, functionally equivalent with good availability and reliability.
