    常見問題解答

    What is LM138K/MIL?

    The LM138K/MIL is a 5A positive voltage regulator IC manufactured by National Semiconductor. It is designed to provide a highly regulated output voltage with a maximum dropout of 3V, making it suitable for applications requiring a stable power supply.

    How Does LM138K/MIL Work?

    The LM138K/MIL operates by maintaining a constant output voltage regardless of changes in input voltage or load conditions. It includes internal circuitry to control the output voltage, providing a reliable power source for various electronic systems. The IC also features built-in thermal shutdown and current limiting to protect against overloading and overheating.

    How Many Pins does LM138K/MIL have and What are the Functions of the Pinout Configuration?

    The LM138K/MIL is available in a TO-3 metal can package with 3 pins. The pinout configuration includes:

    • Input Pin (VIN): Connects to the input voltage source.
    • Output Pin (VOUT): Provides the regulated output voltage.
    • Ground Pin (GND): Connected to the ground reference.

    What are the Pros and Cons of LM138K/MIL?

    Pros:

    • High Current Capability: Capable of delivering up to 5A of output current.
    • Stability: Offers stable output voltage under varying load conditions.
    • Thermal Shutdown: Includes a thermal shutdown feature for overtemperature protection.

    Cons:

    • Voltage Dropout: Has a higher dropout voltage compared to more modern regulators.
    • Package Size: The TO-3 metal can package may be larger and less space-efficient than newer package options.

    Are There Any Equivalents/Alternatives to LM138K/MIL for Recommendation?
