It is designed to reduce power leakage, improve power consistency, reduce device size and deliver reliable power – making it well suited for a broad range of applications, such as industrial equipment and consumer electronics. Here, we will explore the application field, features and working principles of S-13R1D14-A4T2U3.

Application Field

S-13R1D14-A4T2U3 is the ideal carrier-mounted voltage regulator for modern equipment. It is an LDO (Low Dropout voltage Regulator) that can easily regulate and maintain the output voltage levels under varying conditions, allowing for greater control and efficiency. The device is especially useful in electrically noisy and high-temperature scenarios, making it perfect for industrial, automotive and networking equipment applications. Additionally, due to its small size and strong reliability, S-13R1D14-A4T2U3 is an ideal choice for space-constrained battery-powered applications such as smartphones, portable media players, cameras, and other battery-powered products.

Features

S-13R1D14-A4T2U3 offers many features that have made it a preferred choice for electronic device design. Its low-dropout voltage, which is only 290mV, makes it highly efficient and supports higher output currents by minimizing power losses. The device also has minimal power consumption and supports a wide range of input voltages up to 40 volts. It is highly suitable for mobile applications as it has an ultra-low standby current of 1.4uA and can handle load currents up to 1.25A. Additionally, the device is designed to be highly reliable due to its high temperature range capability of –40 ~ 125°C and over-current protection up to 1.35A.

Working Principle

The working principle of S-13R1D14-A4T2U3 is fairly straightforward and is similar to other linear voltage regulators. The device accepts an input voltage ranging from 3V to 40V and adjusts the output voltage as per the user’s needs, which is usually in the range of 1.5V to 6V and can be adjusted using external resistors. The output voltage is regulated using an error amplifier circuit built into the device that compares the “real” output voltage to the reference voltage - which is the voltage desired by the user. If the “real” output voltage is higher or lower than the reference voltage, the amplifier adjusts the circuit to raise or lower the output voltage accordingly. This operation is repeated continuously, ensuring that the output voltage remains consistent, thus delivering reliable power.

Conclusion

S-13R1D14-A4T2U3 is a highly efficient and reliable voltage regulator ideal for a broad range of applications, such as industrial equipment and consumer electronics. By reducing power leakage, improving power consistency, reducing device size, and delivering reliable power, the S-13R1D14-A4T2U3 makes it well suited for both battery-powered and non-battery powered systems. Additionally, the device’s highly efficient and low dropout voltage, as well as its over-current protection features, make it an ideal choice for power supply design. Thanks to its low standby current and wide range input voltages, the S-13R1D14-A4T2U3 is the ideal device for space-constrained, battery-powered devices.
