詳細說明

The L7805ACP is a versatile three-terminal positive regulator that comes in various package options, such as TO-220, TO-220FP, D²PAK, and DPAK. With multiple fixed output voltages available, this regulator is suitable for a wide range of applications. It can provide localized on-card regulation, which helps eliminate distribution issues often associated with single point regulation. Additionally, the L7805ACP features internal current limiting, thermal shut-down, and safe area protection, making it highly durable and reliable. With proper heat sinking in place, this regulator can deliver a maximum output current of over 1 A. While its primary function is as a fixed voltage regulator, users also have the option to customize voltage and current outputs by incorporating external components into the design

主要特徵

  • The L7805ACP linear regulator provides consistent output voltage performance
  • Key advantages include high reliability and low quiescent current consumption
  • A cost-effective solution for applications requiring stable power supplies
    • It has built-in thermal shutdown and short circuit protection features

常見問題解答

What is L7805ACP?

The L7805ACP is a 3-terminal positive voltage regulator IC (integrated circuit) manufactured by STMicroelectronics. It is designed to provide a constant 5V output voltage from a higher input voltage, making it suitable for a wide range of electronic applications.

How Does L7805ACP Work?

The L7805ACP operates by regulating the input voltage to a stable 5V output. It uses internal circuitry to compare the output voltage to a reference voltage and adjusts the pass transistor to maintain the desired output. This ensures that the output remains constant even when the input voltage and load conditions change.

How Many Pins does L7805ACP have and What are the Functions of the Pinout Configuration?

The L7805ACP is housed in a standard 3-lead TO-220 package or a TO-92 package. The pinout configuration includes:

  • Input (VIN): The input voltage is supplied to this pin.
  • Ground (GND): This pin is connected to ground or the negative terminal of the circuit.
  • Output (VOUT): The regulated 5V output is obtained from this pin.

What are the Pros and Cons of L7805ACP?

Pros:

  • Stability: Provides a stable 5V output even with varying input voltages and loads.
  • Widely Available: Widely used and readily available across the electronics industry.
  • Simple to Use: Easy to integrate into circuit designs with minimal external components.
  • Overcurrent and Thermal Protection: Includes built-in overcurrent and thermal shutdown protection.

Cons:

  • Heat Dissipation: May require a heat sink for high current applications due to power dissipation.
  • Dropout Voltage: Requires a higher input voltage than the 5V output, resulting in a voltage dropout.
  • Not Suitable for Low Power: Not efficient for low power applications due to power dissipation.

Are There Any Equivalents/Alternatives to L7805ACP for Recommendation?

  • The LM7805 from Texas Instruments is a direct equivalent to the L7805ACP.
  • Alternatives to the L7805ACP include the UA7805 from Texas Instruments and the 78M05 from Fairchild Semiconductor.
