The S-13R1G28-A4T2U3 is a linear voltage regulator from a family of PMIC (Power Management Integrated Circuit) components. It is an ultra-low voltage regulator that provides a regulated output voltage up to 2.8 V, within a working range of 1.2 V to 3.6 V. This voltage regulator can be used in a wide range of applications, such as automotive, industrial, medical, communications and consumer electronics. In addition, it features ultra-low quiescent current, fast response time and low temperature coefficient.

Application Fields

The S-13R1G28-A4T2U3 is especially suitable for battery operated applications, due to its low quiescent current. It is used in applications such as monitoring, interfaces, analog sensors, power supplies and control systems, among others. Because it has a low quiescent current the voltage regulator is also suitable for low power portable applications, such as portable radios, laptops, mobile phones and digital cameras. If a long battery life is desired, this PMIC component should be included in the design.

Working Principle

The principle of operation of the S-13R1G28-A4T2U3 is relatively simple. The component provides a precise regulated output voltage from its input supply. It achieves this by using an internal voltage divider and then providing a reference voltage to the control circuit, which in turn amplifies and rectifies the output current. The output voltage is then regulated with a transistor, while a parallel capacitor is used to bypass high frequency noise. This combination of circuitry ensures a precisely regulated voltage over a broad range of input voltages.

Benefits of Linear Voltage Regulators

Linear voltage regulators such as the S-13R1G28-A4T2U3 offer several advantages over switch mode power supplies, such as increased efficiency, longer service life and reduced costs. They also provide significant cost savings over power supplies designed specifically for discrete circuits, thanks to their integrated nature. In addition, linear voltage regulators are typically much simpler to use, as compared to switching DC-DC converters, making them an ideal choice for simpler designs.

Conclusion

The S-13R1G28-A4T2U3 linear voltage regulators are a great choice for a range of applications, from automotive to industrial and consumer electronics. With its ultra-low quiescent current, fast response time and low temperature coefficient, it offers efficient, long lasting power conversion with minimal power loss. In addition, its simple design makes it easier to use than other more complex power supplies.
