FAQs
What is LM78L12ACZ?
The LM78L12ACZ is a low-power, fixed voltage regulator IC designed by Texas Instruments. It is part of the LM78xx series of regulators and provides a fixed output voltage of 12V, making it ideal for powering various electronic circuits and devices.
How Does LM78L12ACZ Work?
The LM78L12ACZ operates as a linear voltage regulator that takes an input voltage and provides a stable 12V output voltage regardless of variations in the input voltage or load. It regulates the voltage by dissipating excess power as heat to maintain the desired output voltage level.
How Many Pins does LM78L12ACZ have and What are the Functions of the Pinout Configuration?
The LM78L12ACZ is housed in a TO-92 package with 3 pins. The pinout configuration includes:
- Input (VIN): Input voltage pin.
- Ground (GND): Ground pin.
- Output (VOUT): Output voltage pin (fixed at 12V).
What are the Pros and Cons of LM78L12ACZ?
Pros:
- Fixed Output Voltage: Provides a stable 12V output, suitable for many standard applications.
- Low Cost: Economical voltage regulator solution for basic power supply needs.
- Easy to Use: Simple 3-pin configuration for easy integration into circuits.
- Reliable: Offers voltage regulation and protection features for improved circuit reliability.
Cons:
- Heat Dissipation: May require a heat sink for high current or high voltage differential applications.
- Limited Flexibility: Fixed output voltage may not be suitable for applications requiring variable voltages.
Are There Any Equivalents/Alternatives to LM78L12ACZ for Recommendation?
- The LM7812 from STMicroelectronics is an alternative fixed 12V regulator similar to the LM78L12ACZ.
- Equivalents to the LM78L12ACZ include the UA7812 from Texas Instruments and the L7812CV from STMicroelectronics.
