FAQs
What is L78L12ACZ?
The L78L12ACZ is a positive voltage regulator integrated circuit (IC) designed by STMicroelectronics. It is part of the L78 series of fixed voltage regulators and is specifically configured to provide a regulated output voltage of +12V with a maximum output current of 100mA. The regulator is commonly used in various electronic circuits to provide a stable +12V power supply, especially in low-power applications.
How Does L78L12ACZ Work?
The L78L12ACZ operates as a linear voltage regulator, maintaining a constant output voltage of +12V regardless of changes in input voltage or load variations. It uses a series pass transistor to control the output voltage based on a stable reference voltage and feedback mechanism, ensuring a regulated output. The IC also includes overcurrent and thermal protection features for reliable operation.
How Many Pins does L78L12ACZ have and What are the Functions of the Pinout Configuration?
The L78L12ACZ is housed in a TO-92 package with 3 pins. The pinout configuration includes:
- Input (Vin): The input pin through which the unregulated input voltage is applied.
- Common (GND): The common ground pin for the regulator.
- Output (Vout): The regulated +12V output pin.
What are the Pros and Cons of L78L12ACZ?
Pros:
- Stable Output: Provides a stable and regulated +12V output for powering electronic circuits.
- Overcurrent Protection: Includes overcurrent protection to safeguard the regulator and the connected circuitry.
- Thermal Protection: Features thermal shutdown protection to prevent overheating.
- Simple Configuration: Requires minimal external components for operation, simplifying circuit design.
- Compact Package: The TO-92 package is space-efficient and suitable for applications with space constraints.
Cons:
- Low Output Current: Limited to a maximum output current of 100mA, which may not be sufficient for high-power applications.
- Heat Dissipation: May require a heatsink in high ambient temperature or high power dissipation scenarios.
- Fixed Output Voltage: The output voltage is fixed at +12V and cannot be adjusted.
Are There Any Equivalents/Alternatives to L78L12ACZ for Recommendation?
Possible equivalents to the L78L12ACZ include the LM7812 from Texas Instruments and the UA7812 from Fairchild Semiconductor. These ICs also provide a regulated +12V output with similar characteristics.
