TPS75425QPWPR Application Field and Working Principle

TPS75425QPWPR, which is categorized under PMIC - Voltage Regulators - Linear, is a quad voltage linear regulator that mainly targets low-power multilayered subsystems. It enables system designers to maximize power savings in several ways, allowing them to reduce the losses suffered in many cases due to the excessive voltage drop. Additionally, it also helps in reducing the requirement of power by providing low quiescent current.

The TPS75425QPWPR is an advanced power supply solution that provides high-reliability and superior performance in a wide range of applications including imaging, consumer electronics, networking, automotive and consumer systems. It can provide up to 4 regulated outputs with a regulated output range of 0.6V to 3.3V. In addition, it also features over-voltage protection, over-current protection, and over-temperature protection.

The TPS75425QPWPR operates by using a linear voltage regulator, which essentially works as a voltage divider. A simple voltage divider consists of two resistors set in series, between which is connected the power source from which the regulated output should be obtained. A variable resistor, known as the load resistor, is placed in the center of the divider, and its resistance is adjusted until the desired output voltage is obtained.

The internal regulator consists of an operational amplifier, a power switch, and a voltage reference. The operational amplifier is used to amplify the difference between the output voltage and the reference voltage, while the power switch is used to regulate the amount of voltage that is outputted. The voltage reference is used to set the output voltage and ensures that the output voltage remains constant over a wide range of operating conditions.

The TPS75425QPWPR can also be used in power-supply sequencing applications. In this application, multiple voltage rail outputs are needed and are arranged in a specific order. This can be achieved by connecting the TPS75425QPWPR’s rail outputs in series, and adjusting the output voltage of each rail to the maximum allowed by the next rail.

The TPS75425QPWPR is an ideal solution for powering a wide range of products, as it is capable of offering low quiescent current, fast start-up, low dropout performance, high accuracy, and low output noise. This makes it a popular choice for powering embedded systems and other related applications.
