Introduction

TPS71713DCKR is a positive voltage linear regulator based on Texas Instruments\' Constant-Voltage (CV) technology, designed to provide the ultimate flexibility required by today\'s high performance applications. It has been designed with a low dropout voltage of 300mV and low noise (150 µV RMS) for applications where local DC-DCs can be beneficial. The TPS71713DCKR is a simple, cost effective solution for delivering a regulated 5V output from a wide range of input voltage sources. It includes features such as low quiescent current, reverse current protection, over current protection, and high efficiency operation.

Features

The TPS71713DCKR features a wide input voltage range of 4.5V to 16V to cover all the common input voltage sources. It also has a low quiescent current of only 4.5mA, allowing it to be used in battery powered applications. It has a low drop-out voltage of 300mV and its output current of 1.5A can be used either in a linear or in pulsed mode. The TPS71713DCKR is protected against reverse current and over current conditions and it has a shutdown pin that can be used to turn it off when not in use. It is also thermally protected and has inherent ESD protection.

Application field

The TPS71713DCKR is suitable for a variety of applications such as mobile phones, notebooks, tablets, embedded systems, digital TVs, gaming devices, industrial equipment, automotive electronics, medical devices and many more. It is particularly applicable for applications where very low quiescent current, low noise and high output current are needed.

Working principle

The TPS71713DCKR works by constantly controlling the output voltage applied to the load. The device implements a simple control loop which adjusts the output voltage according to the input voltage. When the input voltage rises above the output voltage, the output current is increased, and when the input voltage drops below the output voltage, the output current is decreased.This is done using a voltage sensing feedback circuitry which monitors the output voltage of the device, and an internal error amplifier constantly compares the output voltage to a reference voltage. When the output voltage rises above the reference voltage, the error amplifier closes the loop and increases the output current. Conversely, when the output voltage drops below the reference voltage, the error amplifier reopens the loop and decreases the output current.The TPS71713DCKR also implements several protection features such as over-current and thermal protection, allowing the device to easily handle a wide range of input and load conditions. Overall, the TPS71713DCKR is an ideal choice for applications that require a low dropout voltage regulator with low quiescent current and high current output.

Conclusion

In conclusion, the TPS71713DCKR is an ideal choice for applications requiring low dropout voltage, low quiescent current, high efficiency and high output current such as mobile phones, notebooks, embedded systems and automotive electronics. The device has a wide input voltage range and can be used in battery powered applications. Its features such as reverse current protection, over current protection and shutdown pin add to its versatility and make it suitable for many different applications.
