Working Principle of the SG7915K-JAN

The SG7915K-JAN is a voltage regulator with a linear type architecture. This type of regulator acts as an electronic buffer between the input source of unregulated voltage and the device requiring the regulated output voltage. The SG7915K-JAN operates in a feedback loop, where the regulated output voltage is compared to a reference voltage, and the voltage difference is amplified which then controls the output voltage. In order to maintain a stable output voltage, the SG7915K-JAN has an internal error amplifier and a feedback network, which adjusts the output voltage as necessary.

The SG7915K-JAN also features an internal protection circuit, which prevents the output voltage from exceeding its over voltage limit, or dropping below its under voltage limit. In addition, it has an over-temperature protection feature, which will trip at temperatures of up to 120°C.
