Working Principles

The S-1135A20-A6T1U is a linear voltage regulator that utilizes a PNP transistor as the pass element. It regulates the output voltage by adjusting the resistance between the input and output pins. When the input voltage exceeds the desired output voltage, the pass element reduces the resistance to maintain a stable output. Conversely, if the input voltage drops below the desired output voltage, the resistance increases to compensate for the difference.

Detailed Application Field Plans

The S-1135A20-A6T1U is commonly used in portable electronic devices such as smartphones, tablets, and wearable devices. Its low dropout voltage and small package size make it ideal for battery-powered applications where space is limited. Additionally, it finds application in automotive electronics, industrial equipment, and various consumer electronics.
