Technical Specifications:

The KIA78L15BP has a fixed output voltage of 15V with a specified tolerance. It requires a minimum input voltage slightly higher than 15V to maintain regulation. The maximum input voltage is limited to prevent damage to the regulator. The device provides a maximum output current, typically around 100mA. Thermal considerations are important, and a heat sink may be required depending on the input voltage, output current, and ambient temperature.

Refer to the KEC datasheet for detailed specifications, including input voltage range, output voltage tolerance, output current limits, thermal resistance, and operating temperature range. Proper decoupling capacitors are recommended on the input and output to improve stability and reduce noise. The datasheet also provides application notes and example circuits for various uses.
