TPS79901DRVRG4 Working Principle

TPS79901DRVRG4 is a low input voltage, low dropout linear regulator designed to maintain its output voltage at 1.2V. The device is designed with a 20µA low dropout voltage and a logic-controlled power-down function. The device also features adjustable soft-start and remote sensing, enabling better transient response and output voltage accuracy. The input voltage starts from 0.9V up to 5.5V, making it ideal for a variety of applications.

TPS79901DRVRG4 consists of an external NMOS pass transistor and a feedback circuit to provide output regulation. The output voltage is determined by an external resistor divider. When the output voltage is higher than the target, an internal pass transistor is turned off and the feedback circuit is opened. The external NMOS pass transistor becomes the only conducting path, reducing the output voltage until it reaches the target level.

When the output voltage is lower than the target, the internal pass transistor is turned on and the feedback circuit is closed. The external NMOS pass transistor is pulled up by the feedback circuit, and the output voltage is increased until it reaches the target level. Additionally, the TPS79901DRVRG4 features a low dropout voltage, which is 20µA, meaning the device is able to efficiently regulate the output voltage even when the input voltage is close to the target. Furthermore, the device includes a built-in power-down feature, which provides an extended operation range.

TPS79901DRVRG4 is a versatile, efficient, and reliable voltage regulator that is ideal for a variety of applications where space and efficiency are critical elements. It is an ideal solution for cell phones, PDAs, digital cameras, Bluetooth devices and other portable electronic devices.
