詳細說明
The KA78XX/KA78XXA series of three-terminal positive regulator are available in the TO-220/D-PAK package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.Features• Output Current up to 1A• Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V• Thermal Overload Protection• Short Circuit Protection• Output Transistor Safe Operating Area Protection

常見問題解答
What is KA7805R?
The KA7805R is a positive voltage regulator integrated circuit (IC) designed by Fairchild Semiconductor. It is part of the 78xx series of fixed linear voltage regulators and is capable of providing a stable 5V output voltage from a higher input voltage. The IC is commonly used in various electronic circuits to ensure a reliable and constant 5V power supply.
How Does KA7805R Work?
The KA7805R works by taking an input voltage that is higher than the desired output voltage (in this case, 5V) and regulating it down to a stable 5V output. It accomplishes this through internal circuitry that compares the actual output voltage to a reference voltage and adjusts the output to maintain the desired 5V level. This regulated output voltage can then be used to power other components within the circuit.
How Many Pins does KA7805R have and What are the Functions of the Pinout Configuration?
The KA7805R is housed in a standard 3-pin TO-220 package. The pinout configuration includes:
- Input (VIN): The input pin for the higher voltage to be regulated down to 5V.
- Ground (GND): The ground pin for the regulator.
- Output (VOUT): The regulated 5V output pin.
What are the Pros and Cons of KA7805R?
Pros:
- Stable Voltage Output: Provides a stable 5V output voltage, suitable for powering various electronic components.
- Low Cost: Generally available at a low cost, making it a cost-effective voltage regulation solution.
- Simple to Use: Requires minimal external components for basic operation, making it easy to integrate into designs.
Cons:
- Heat Dissipation: May require a heat sink for higher current applications due to power dissipation.
- Fixed Output Voltage: The 5V output is not adjustable, limiting flexibility in some applications.
Are There Any Equivalents/Alternatives to KA7805R for Recommendation?
Similar alternatives to the KA7805R include the L7805 from STMicroelectronics and the LM7805 from Texas Instruments, both of which are part of the 78xx series of voltage regulators.
