The working principle of the S-1165B37MC-N6WTFU linear regulator is quite simple. It utilizes the principle of voltage regulation, which can be expressed mathematically by the following equation: Vout = Vin – Vdrop + Iload x Rload, where Iload is the load current, and Rload is the load resistance. Essentially, the linear regulator acts as a variable resistor, with its resistance being adjusted in order to maintain a constant output voltage. This is accomplished by varying the internal transistor’s base current in response to changes in the input voltage. The transistor is then switched ON and OFF at a specific frequency such that the load voltage remains constant.

The S-1165B37MC-N6WTFU linear regulator is an excellent choice for applications that require a stable and reliable power source even when the voltage level drops very low. Its features make it suitable for a variety of applications, and its working principle is simple yet effective, making it an appealing option for a wide range of users.
