Applications

The S-13R1G24-A4T2U3 is an ideal voltage regulator solution for a variety of battery operated and industrial applications such as laptops, mobile phones, digital cameras, DVD players, motor vehicles and more. It is especially well suited to LED lighting applications since it requires no additional current limiting circuitry and has a low quiescent current and high efficiency linear regulator. It is also highly suitable for use in consumer audio/video & networking applications, because of its extremely low EMI which eliminates the need for costly shielding.

Working Principle

The S-13R1G24-A4T2U3 integrates a standard linear voltage regulator circuit and uses an internal high accuracy series reference voltage to provide stable and consistent output regulation. It\'s main elements are a voltage reference, an error amplifier, a driver stage, and a series pass element. The voltage reference provides a stable output reference voltage, the error amplifier compares the input voltage with the output voltage through the voltage reference and then amplifies the error signal, the driver stage amplifies the error signal to increase current output and the series pass element controls the current to the output based on the error signal.

The S-13R1G24-A4T2U3 also includes internal current limiting and thermal overload protection, which prevent any potential damage to the system under overload conditions. Under overload conditions, current limiting is activated and the output current is limited to a safe level while the thermal overload protection regains thermal equilibrium by reducing the output voltage and shutting off the output pin. Once the overload condition has been removed and the temperature decreased to preset levels, the IC resumes normal operation.

Conclusion

The S-13R1G24-A4T2U3 is a high-performance, highly efficient, and low cost solution for many system power management applications. By integrating current limit and thermal protection, it provides users with a complete power management solution for their products. Its wide input and output range makes it ideal for many consumer and industrial applications, while its robust current limit protection and low EMI make it suitable for use in audio/video and networking applications. Its low quiescent current and high efficiency linear regulation make it well-suited for use in LED lighting applications.
