TPS79628DCQR is a low quiescent current and high precision linear voltage regulator, whose application fields and working principles are widely used. It is generally classified under PMIC - Voltage Regulators - Linear.

TPS79628DCQR belongs to a series of low-dropout (LDO) linear voltage regulator devices and is designed for use in automotive, battery and general purpose applications. It is designed to provide up to 1.5A of continuous load current and up to 3A peak load current. The device incorporates advanced short circuit protection, over-temperature protection and over-current protection.

In terms of application fields, TPS79628DCQR can be widely used in automotive, motorcycle, ATV, portable media players, PND, Camera, LCD and other applications. This device offers a high precision output , low quiescent current and wide operating temperature range of -40°C∽125°C.

TPS79628DCQR also eliminates the need for multi voltage regulator components, which further reducing the power consumption of mobile systems. Its high PSRR and low noise also allows the device to operate in noisy environments, such as digital radio, audio amplifiers and other portable applications.

The working principle of TPS79628DCQR is relatively simple. It uses a feedback circuit to measure the output voltage, and compares this voltage to the reference voltage. The difference between the two signals is then used to regulate the output voltage. It achieves its regulation by controlling the current flow through a pass transistor, which is connected between the input and output of the regulator.

When the desired output voltage is reached, the device transitions into a low quiescent current state, reducing the power consumption. At the same time, when the output current increases, the device automatically increases the output voltage in order to maintain the stability of the output. This allows the device to remain stable over a wide range of load current, making it suitable for many applications.

In summary, TPS79628DCQR is a very useful and reliable linear voltage regulator, which can be widely used in high-precision and high current applications, such as automotive, motorcycle, portable media players, PND, Camera, LCD and other applications. It is a low quiescent current and high precision linear voltage regulator, so it can be classified under PMIC - Voltage Regulators - Linear.
