SG109T-JAN is a linear voltage regulator which is classified as part of PMIC (Power Management IC). It uses advanced body bias technology and shallow trench isolation (STI) to create and provide small handheld devices with low-cost power management solutions. It offers excellent accuracy, high efficiency and low power loss compared to other linear voltage regulator ICs.

SG109T-JAN has applications in many different fields such as PCs, home and office appliances, cars, mobile phone accessories and electronic equipment, to name just a few. Its small size (3.3mm x 3.8mm) makes it suitable for various small-scale projects and makes it especially suitable for portable applications.

The primary benefit of SG109T-JAN is that it boosts the battery life of portable systems by efficiently managing the voltage level. It works by controlling the voltage level of the system, ensuring it doesn’t exceed certain thresholds. The output is determined by the reference voltage at the input. SG109T-JAN can be connected in parallel to increase current capacity, or serial to increase output voltage.

SG109T-JAN works on the non-synchronous boost principle. The input VIN provides the required charge to the SG109T-JAN, and the reference voltage VREF provides a control input. First, the switching transistor M1 turns on and saturates. Then, the current will flow into the inductor L1 and the input capacitor CIN, charging it until the voltage at the inductor L1 reaches the voltage at the reference input. At this point, the switching transistor M1 turns off and the output capacitor can discharge.

The reference voltage, which determines the output voltage, is provided by the main system, so it isn’t dependent on the battery voltage. This provides the user with great flexibility, allowing the output voltage to be easily adjusted to meet system requirements.

The SG109T-JAN is capable of delivering an output current up to 500mA, and the output voltage can be adjusted from 1.8V to 5V. That makes it an ideal choice for applications where a low output voltage is required. It also has great efficiency for typical use cases, up to 96%.

The SG109T-JAN is a popular choice for USB charging applications due to its high-efficiency and low power loss. It is also frequently used as a battery charger, providing a constant voltage input to the battery while also preventing battery overcharge.

In summary, SG109T-JAN is a linear voltage regulator that excels at providing efficient and reliable power management solutions for a variety of applications. It is capable of providing a wide range of output currents and voltages, making it suitable for many different applications. Its small size and low power consumption make it an ideal choice for portable devices with limited space. Furthermore, its advanced body bias and shallow trench isolation technology makes for a highly reliable and efficient regulator.
