Working Principle

The S-13R1G15-A4T2U3 operates in linear voltage regulation mode. This means that it regulates the output voltage by controlling the amount of current flowing through the output stage. At the start of operation, the output voltage is set to the desired level. The error amplifier compares the actual output voltage and the desired output voltage, generating an error signal. This signal is used to control the current through the output stage, maintaining the output voltage at the desired level. The S-13R1G15-A4T2U3 has a low dropout voltage, allowing it to maintain regulation at very small input-to-output voltage differences. The device is protected against reverse current, short circuit, and over temperature. It also has an integrated current limit circuit, which prevents the output stage from delivering excessive current.
