Working Principle
The S-1721A2812-I6T1U linear voltage regulator works by controlling the input voltage, which then controls the output voltage. This is achieved by a controllable FET that is placed between the input and output. When the input voltage is greater than the output voltage, the FET is open and all of the current is passed through to the output. If the input voltage is lower than the output voltage, the FET will close and current will be drawn from the output, causing the output voltage to be lower than the input voltage. This state can be regulated by controlling the gate voltage of the FET, which is typically done with a voltage regulator circuit.
The S-1721A2812-I6T1U also contains several additional features that help increase efficiency and protect from damage. The soft start and current limiting features, for example, help to reduce inrush current and protect the performance of the circuit. The over current protection feature will shut down the device should it detect a current overload. The thermal shutdown feature will also shut down the device should it detect an overheating condition.
