Working Principles

The S-1172B1E-E6T1U 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 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 maintain regulation.

Detailed Application Field Plans

The S-1172B1E-E6T1U is commonly used in various electronic devices that require stable and accurate voltage regulation. Some typical application fields include: - Battery-powered devices (e.g., smartphones, tablets) - Portable audio players - Wearable devices - IoT modules - Industrial control systems
