Introduction

The S-13R1A36-A4T2U3 is a voltage regulator designed to control the maximum output voltage of a device or system. It is a linear regulator and is most commonly used to provide a constant output voltage, even in the presence of disturbances in input voltage. This pmic voltage regulator is designed to have better performance than intermediary chip (PMIC) voltage regulators, due to its efficient use of energy and its ability to maintain a constant output voltage even under varying input voltages.

Application Field and Working Principle

The S-13R1A36-A4T2U3 linear regulator is most often used in systems where the output voltage needs to be controlled by a voltage regulator with a constant output voltage. Typical applications for this device include automotive systems, mobile phones, medical devices and computers.

Linear regulators work by comparing their input voltage to a reference voltage and blending the two voltages to maintain a constant output voltage. This is known as the ‘Error Amplifier’ function. The comparison of the input voltage to the reference voltage creates an ‘error signal’, which is then fed to an output control circuit, which modulates the output voltage.

This device has a switch mode that is used as part of the ‘error amplifier’ function. This switch mode ensures that the output voltage remains constant regardless of changes in input voltage. This is why it is suitable for controlling output voltages in applications where the input voltage is highly variable.

In addition to the ‘error amplifier’ function, the S-13R1A36-A4T2U3 also includes a temperature protection circuit. This circuit enables the device to operate safely within a specified temperature range, ensuring that it does not become too hot and cause damage to components.

Features

The S-13R1A36-A4T2U3 has a variety of features that make it suitable for various applications. It is designed to have high accuracy, low quiescent current and a wide input voltage range. It has an output current of up to 3A and a maximum operating temperature of up to 135°C.

Other features include reverse-blocking protection which prevents output reverse current, and over-temperature protection which prevents the device from becoming too hot. The device also includes Protection against Short Circuit (SCP) and Overload (OLP) which protect the device from damage if the output voltage is outside the specified range.

The S-13R1A36-A4T2U3 also provides a wide output voltage range, from 1V to36V, allowing it to be used for a variety of applications. Another important feature of this device is its high power rating, up to 20 W. This makes it suitable for applications that require high amounts of power.
