Details
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.
The KA7810A is a widely-used voltage regulator IC developed by Fairchild Semiconductor (now part of ON Semiconductor). It is designed to provide a stable and regulated output voltage of 10V from a higher input voltage, making it suitable for a range of electronic applications where reliable voltage regulation is required. The KA7810A is part of the 78xx series of linear voltage regulators, known for their ease of use and dependable performance.
Key Features
- Type: Linear voltage regulator.
- Input Voltage Range: Operates with an input voltage typically from 12V to 35V, providing a regulated output of 10V.
- Output Voltage: Fixed output voltage of 10V with a tolerance of ±4%.
- Output Current: Capable of supplying up to 1.5A of continuous output current.
- Dropout Voltage: Typical dropout voltage is around 2V, which allows for efficient operation with a reasonable difference between input and output voltages.
- Thermal Protection: Includes thermal shutdown to prevent damage from overheating.
- Overcurrent Protection: Equipped with internal current limiting to protect against excessive current draw.
- Package Type: Available in various package types such as TO-220, TO-3, and TO-92, for easy integration into circuit designs.
