Overview
Description
Packaged typically in a TO-220 form factor, the LM7912CT is suitable for various applications, including consumer electronics, automotive systems, and industrial equipment. Its ability to maintain a consistent voltage output makes it essential for circuits where precise voltage regulation is crucial, such as in audio equipment and power supply units.
Key specifications include an input voltage range of -14.5V to -35V, a maximum output current of 1.5A, and a dropout voltage of about 2V. The LM7912CT is favored for its robustness, ease of use, and cost-effectiveness, making it a popular choice for engineers and hobbyists alike.
Features
1. Negative Voltage Regulation: It provides negative voltage regulation, making it suitable for dual-supply applications.
2. Output Voltage: Fixed -12V output, eliminating the need for external components for voltage adjustment.
3. Current Capacity: Can deliver up to 1.5A of output current.
4. Thermal Overload Protection: Built-in protection against overheating, ensuring reliable operation under varying conditions.
5. Short-Circuit Protection: Includes short-circuit protection to prevent damage from excessive current draw.
6. Safe Operating Area (SOA) Protection: Ensures the device operates within safe limits, enhancing reliability.
7. Input Voltage Range: Requires a minimum input voltage of approximately -14.5V to function correctly, and can handle higher input voltages up to -35V.
8. Package: Available in a TO-220 package, providing a robust solution for various applications.
These features make the LM7912CT ideal for use in power supply designs where a stable negative voltage is essential.
Package
Pinout
1. Pin 1 (Input): This pin is where the unregulated input voltage is supplied. The input voltage must be more negative than the output voltage (typically more negative than -14V) for proper regulation.
2. Pin 2 (Ground): This is the ground pin, which serves as a common reference point for the input and output voltages.
3. Pin 3 (Output): This pin provides the regulated output voltage of -12V. It is connected to the load that requires the regulated voltage.
The LM7912CT is commonly used in power supply circuits to provide a stable -12V output for various electronic applications, ensuring consistent performance despite variations in input voltage or load conditions.
