Application Field
The S-1112B17PI-L6CTFU is designed for applications such as high-accuracy and low-noise supply of processors and other integrated circuits. The adjustable voltage regulator is ideal for use in a wide range of electronic products and equipment such as cellular phones, portable computers, digital still cameras, PDA’s, portable video players, printers, and test and measurement equipment. It is also suitable for voltage stabilization applications that require high current capability and low dropout voltage. The device is especially suitable for high-performance systems that require a minimum supply voltage.

Working Principle
The basic principle of operation of the S-1112B17PI-L6CTFU is simple and well-understood. The device works by controlling the voltage output of a power supply. It uses a “P-type” linear voltage regulator, which works by subtracting a reference voltage (Vref) from the supply voltage (Vinput) to provide the output voltage (Vout). By changing the value of Vref, the output voltage can be adjusted as required. This is done by connecting a resistor network to the reference pin; the value of the resistors determines the value of Vref. The voltage is regulated by controlling the current through a P-type FET, which is connected between the supply voltage and the reference voltage.
