FAQs

What is LM7810CT?

The LM7810CT is a 10V positive voltage regulator integrated circuit (IC) manufactured by Texas Instruments. It is designed to provide a stable 10V output voltage from a higher input voltage, making it suitable for powering various electronic circuits and components.

How Does LM7810CT Work?

The LM7810CT works by regulating the input voltage to a steady 10V output voltage, regardless of variations in the input voltage or changes in load current. It utilizes internal circuitry to achieve this voltage regulation, ensuring a reliable power supply for connected devices.

How Many Pins does LM7810CT have and What are the Functions of the Pinout Configuration?

The LM7810CT is housed in a 3-pin TO-220 package. The pinout configuration includes:

  • Input (VIN): The input pin where the unregulated voltage is applied.
  • Ground (GND): The ground pin, which is connected to the reference voltage of the circuit.
  • Output (VOUT): The regulated 10V output pin.

What are the Pros and Cons of LM7810CT?

Pros:

  • Stable Output: Provides a consistent 10V output voltage, suitable for powering sensitive components.
  • Simple to Use: Requires minimal external components for voltage regulation.
  • Wide Input Voltage Range: Can accept a wide range of input voltages for versatility.
  • Thermal Shutdown Protection: Includes thermal shutdown and current limiting for overheat protection.
  • Low Cost: Offers a cost-effective solution for voltage regulation.

Cons:

  • Wasted Power: Operates in a linear mode, which may result in higher power dissipation for large voltage differentials.
  • Heat Dissipation: May require a heat sink for applications with higher power dissipation.

Are There Any Equivalents/Alternatives to LM7810CT for Recommendation?

  • The LM340-10 from Texas Instruments is a pin-to-pin equivalent alternative to the LM7810CT.
  • Alternatives to the LM7810CT include the UA7805 from Texas Instruments and the L78S10CV from STMicroelectronics.
