S-13R1C40-N4T1U3 linear voltage regulation is based on a basic principle of using a pass transistor (usually a Field Effect Transistor) between the input voltage supply and the load to limit the current flow. The transistor is controlled by feedback from the regulated output voltage. When the output voltage starts to drop, the pass transistor turns on and increases the output current from the regulated voltage supply. This action increases the voltage drop across the pass transistor and increases its on-state resistance, thereby reducing the output current and bringing the output voltage back to its desired level.

For the S-13R1C40-N4T1U3, the pass transistor is a standard MOSFET with a built-in current limit protection. The current limit protection is triggered by excessive current through the MOSFET, causing the over current protection pin to indicate high. In this case, the pass MOSFET reduces power until the current limit has been dispersed. The current limit is adjustable so that the maximum output current can be set according to the application requirements.

In summary, the S-13R1C40-N4T1U3 is a linear voltage regulator specifically designed for low dropout and high efficiency applications. It is available in both surface mount and through-hole packages, and its wide range of safety features make it ideal for use in sensitive medical applications. Its low dropout voltage and low temperature coefficient ensure precise control of the regulated output voltage. Due to its wide input voltage range, the S-13R1C40-N4T1U3 is also suitable for automotive applications, providing reliable protection and current limiting capabilities.
