Features
1. Output Voltage: It provides a fixed output voltage of 12V.
2. Output Current: The regulator can supply a maximum output current of 0.5A.
3. Input Voltage: It requires an input voltage greater than the output voltage, typically between 14.5V to 35V.
4. Thermal Protection: The device includes built-in thermal shutdown to protect against overheating.
5. Short-Circuit Protection: It features current limiting to protect against short circuits.
6. Internal Thermal Overload Protection: Ensures the device operates within safe temperature limits.
7. Low Dropout Voltage: It has a relatively low dropout voltage, enhancing efficiency.
8. Mounting Type: The L78M12CDT comes in a TO-252 (DPAK) package, suitable for surface mount technology.
9. Applications: Commonly used in power management for consumer electronics, industrial applications, and other circuits requiring a stable 12V supply.
These features make the L78M12CDT suitable for a variety of applications where stable voltage regulation is needed.
Pinout
1. Input (Pin 1): This is where the unregulated input voltage is applied. It should be higher than the desired output voltage to ensure proper regulation.
2. Ground (Pin 2): This pin is connected to the circuit ground. It is the reference point for the input and output voltages.
3. Output (Pin 3): This pin provides the regulated output voltage. For the L78M12CDT, the output is fixed at 12V.
The L78M12 series is known for providing a stable output voltage with a current capability of up to 0.5A and includes internal features such as thermal shutdown and short-circuit protection, which enhance the reliability of circuits using this regulator.
