The TPS73410DDCT is a Low-Dropout (LDO) voltage regulator designed to provide a higher level of accuracy, output current, and low-quiescent current compared to bulky, high quiescent linear regulators. The device offers a wide range of output voltage range from 1.2V to 15V, with an adjustable voltage accuracy as low as ±4mV, using only a single resistor.

Application Field

TPS73410DDCT has a wide range of applications, primarily in consumer electronics. Its low quiescent current makes it an ideal choice for portable PCs and mobile phones. The device also finds its use in other consumer electronics like LED backlighting, plasma displays, audio components, gaming consoles, medical equipment, automotive, and industrial electronics.

The TPS73410DDCT LDO voltage regulator is also suitable for use in automobiles, providing stable and accurate voltage to automotive loads like alternators, dashboard gauges and navigation systems. Due to its low dropout voltage, it is also suitable for applications requiring high-efficiency voltage conversions from 12V to 5V and 3.3V.

Working Principle

The basic working principle of the TPS73410DDCT LDO voltage regulator is based on a current mirror or current source connected to a voltage reference. The voltage reference is usually a Bandgap reference, which produces a precise and relatively stable reference voltage and temperature coefficient over a wide range of operating conditions. The current mirror uses this reference voltage to generate a precise, constant current level, which is used to drive the output device.

The output device is usually a P-channel MOSFET, which has two input terminals: the drain and the gate. The TPS73410DDCT LDO voltage regulator sets the voltage at the drain terminal to the precise, adjustable output voltage. The gate terminal is then connected to the output node, where the output voltage is fed to the downstream load. The voltage regulator then controls the current mirror, to ensure that the output voltage remains stable and accurate.

In addition, the TPS73410DDCT LDO voltage regulator also features features various levels of over voltage protection and thermal shutdown, which ensures that the device does not receive any undue damage due to component or overload stress. This is particularly important in applications where the device is subject to long-term use or high temperature environments.

The TPS73410DDCT LDO voltage regulator is a reliable and efficient voltage regulator, suitable for a wide range of consumer and industrial applications. With its high accuracy and easy implementation, it is an ideal choice for power supply solutions.
