TPS76301DBVR application field and working principle

TPS76301DBVR is a low dropout positive voltage regulator and low quiescent current linear regulator developed by Texas Instruments, which can be used to provide an accurately regulated supply voltage with a very small line and load regulation. It belongs to the PMIC - Voltage Regulators - Linear category. It is suitable for providing an accurate 0.8V to 5V output voltage with a maximum output current of 300mA and a maximum dropout voltage of 300mV. In addition, it has a low current of 700μA in sleep mode.

Application

TPS76301DBVR can be used in a variety of portable or industrial applications that require an accurately regulated voltage to power an IC or other device, such as cell phones, PC/notebook/ tablet PC peripherals, quick-charging circuits, printer circuits and low current applications. Its low quiescent current, low dropout voltage, excellent stability, and wide input voltage range make it the perfect choice for many regulated voltage applications.

Working principle

In order to meet its excellent performance, the internal circuitry of TPS76301DBVR can be divided into two parts: the voltage reference circuit and the error amplifier circuit. The voltage reference circuit is based on linear CMOS technology and can provide a very precise voltage reference voltage at the output. While the error amplifier circuit is used to detect the voltage difference between the output voltage feedback and the reference voltage, and then make the necessary adjustments on the output voltage in order to keep its accuracy.

In addition, the output potential of the chip is determined by the other voltage setting pins such as the positive voltage input pin, feedback pin, and adjustable voltage reference pin. All these voltage setting pins play an important role in setting the output potential of the chip and ensuring its accuracy. For example, the input pin voltage determines the voltage range of the output voltage. And the feedback pin voltage and the adjustable reference pin voltage will adjust the output voltage accordingly.
