Working Principle

The working principle of the S-13R1C31-A4T2U3 is similar to other linear voltage regulators. The device works by regulating the output voltage to the desired level by controlling the amount of current that is passed through the pass transistor. The control of the current is implemented by feedback mechanism, which compares the output voltage to reference voltage and modifies the pass transistor current accordingly. During normal operation, the input voltage typically must be higher than the regulated output voltage so that the pass transistor can operate properly, otherwise the output voltage could not be maintained.

The low dropout voltage regulator provides high power output capability and very low quiescent current. It also offers reverse current protection and short-circuit protection. The output voltage accuracy of the device is very high and can reach 0.4%.
