Working Principles

The S-1135C28-A6T1U 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 is higher than the desired output voltage, the pass element conducts and maintains a stable output voltage. The regulator continuously monitors the output voltage and adjusts the resistance to compensate for any changes in load or input voltage.

Detailed Application Field Plans

The S-1135C28-A6T1U is suitable for various applications that require a regulated power supply with low dropout and high current capabilities. Some potential application fields include: - Portable electronic devices (e.g., smartphones, tablets) - Battery-powered systems - Wireless communication devices - Industrial control systems - Automotive electronics
