Working Principle

The S-1137B35-I6T2U is a 3 Amp, fixed Linear Voltage Regulator. It is based on a traditional buffer/level shifting architecture and can operate in a wide input voltage range, up to 7V. It features an adjustable voltage limit for pre-set voltage setting and can also be used in a switch mode design for power efficiencyThe device has two main parts - a control circuit and the output section. The control circuit is responsible for regulating the input voltage. It consists of an internal voltage reference and an error amplifier. The error amplifier senses any differences between the reference and input voltage, and compares them. The output of the error amplifier is then used as the final output voltage.The output section of the S-1137B35-I6T2U is made up of an NPN transistor, a PNP transistor and a series resistor, which are all connected to the output of the error amplifier. This series resistor is used to adjust the output current in order to maintain the output voltage at the pre-set level.
