Working Principles

The S-1135D31-U5T1G is a linear voltage regulator that uses a PNP transistor as the pass element. It regulates the output voltage by adjusting the resistance between the input and output terminals. When the input voltage exceeds the desired output voltage, the pass element reduces the resistance to maintain a stable output. Conversely, when the input voltage drops below the desired output voltage, the pass element increases the resistance to compensate and provide a constant output voltage.

Detailed Application Field Plans

The S-1135D31-U5T1G is commonly used in various battery-powered electronic devices, such as: - Mobile phones - Portable media players - Digital cameras - Wearable devices - Wireless sensors
