<h2> Introduction </h2><p>TPS7225QDG4 is a voltage regulator with high efficiency and low quiescent current. It is the ideal choice for wide input range applications, including automotive and consumer electronics. With its adjustable output voltage, it is suitable for a variety of voltage regulation applications. This article will provide an overview of the application field and working principle of the TPS7225QDG4.</p><h2>Application Field </h2><p>The TPS7225QDG4 is a CMOS low power voltage regulator. The Quiescent Current in this device is only 0.5~1.5uA, making it suitable for portable and battery operated applications with long run times. The device can be used for a wide input voltage range from 2V to 6V, making it ideal for automotive and consumer electronics design. The device is capable of sourcing up to 0.5A load with a dropout voltage of only 170mV at 0.5A load. The output voltage is adjustable from 1.235V to 2.8V, making it suitable for a variety of voltage regulation applications. The device features short circuit and thermal protection, making it an ideal choice for safety-critical applications.</p><h2>Working Principle </h2><p>The TPS7225QDG4 works by using an internal pass element to control the output voltage. The rate of current flow through the pass element is controlled by an external voltage divider. This divider is used to sense the output voltage and adjust the current flowing through the pass element to keep the output voltage constant. The device has two enable pints that can be used to enable and disable the device. When enable pin is low, the output of the device is turned off.</p><h2>Conclusion </h2><p>The TPS7225QDG4 is an ideal solution for voltage regulation applications. It is an efficient and low power device with a wide input voltage range and adjustable output voltage. It is suitable for safety-critical applications, featuring short circuit and thermal protection. The device is capable of sourcing up to 0.5A load with a dropout voltage of 170mV at 0.5A load.</p>
