AP2138N-2.1TRG1 series of voltage regulator is a linear voltage regulator in the PMIC (Power Management IC) family. It is designed to offer efficient and precise output voltage regulation with managed current protection in both low and high load applications. This product is aimed at providing stable and precise regulated output above the regulated threshold. It provides precise and adjustable output voltage in the range of 0.8V to 5.5V with 0.1V adjustability.

The working principle of AP2138N-2.1TRG1 voltage regulator is quite simple. The series consists of an integrated voltage reference, an adjustable voltage setting resistor, and a series of cascaded power transistors. A reference voltage is supplied to the regulator when the input voltage exceeds the required output voltage. The reference voltage is compared with the adjustable voltage setting resistor, and the output voltage is automatically adjusted in response to the difference. This allows the regulator to maintain a precise output voltage even when the input voltage fluctuates.

AP2138N-2.1TRG1 voltage regulators are suitable for applications where precise output voltage is required. It is particularly suitable for battery-powered portable devices and consumer products such as notebooks, PDA’s and mobile phones. Moreover, it is also suitable for a wide range of applications including industrial, automotive, aerospace, and medical systems. In addition, it can also be used for controlling CPU voltage, overvoltage protection, and voltage-boosting.

Moreover, AP2138N-2.1TRG1 voltage regulators offer many advantages over traditional regulators. Firstly, they are cost effective compared to other linear voltage regulator and provide better voltage regulation in terms of both load and line regulation. Secondly, their adjustable output and wide range of output voltages make them ideal for applications requiring a precise control output. Finally, the series has superior spike handling and noise immunity, which allows them to maintain a reliable performance even in the presence of transients and high-noise environments.

In conclusion, AP2138N-2.1TRG1 voltage regulators are a cost effective and precise linear voltage regulator with superior spike handling and noise immunity capabilities. They are suitable for applications requiring precise output voltage regulation in both low and high-load conditions and are ideal for a wide range of applications including portable devices, consumer products, industrial, automotive and aerospace systems.
