Working Principle

The S-1312D10-A4T2U3 voltage regulator has a wide input voltage range, allowing it to provide a regulated 10 V output voltage even when the input voltage range varies from 6 V to 24 V. The device uses a combination of components in order to achieve this. A pass element, typically a power transistor, is the main component of the regulator and handles the current flow to the output. An error amplifier is used to compare the output voltage to an internal reference voltage and adjust the output accordingly. A feedback loop is established between the amplifier and the pass element in order to accurately maintain the desired output voltage over a wide range of input voltages. The voltage regulator has current limiting and thermal shutdown protection to ensure safety and prevent damage due to excessive current or overheating.
