TPS73HD318PWP, a voltage regulator whose output voltage is 3.3V, belongs to the Linear Voltage Regulator subfamily of PMIC (Power Management IC). With its 17V rated maximum input voltage, it is suitable for use in many power supply applications including battery operated devices, automotive applications, and other applications with a wide input voltage range.

The wide voltage range is possible with the positive-ended output configuration of TPS73HD318PWP. It has an on-board set-point precision reference and provides a high output current (1A maximum) with a low quiescent current of 40µA. It is designed for high-efficiency operation with very low output voltage ripple and a wide temperature range of -40°C to +85°C.

TPS73HD318PWP uses a three-terminal feedback loop architecture to achieve a wide range of load regulation capabilities. The device can regulation load up to 300mA, with an output DC tolerance of ±3mV. The output voltage is adjustable with an external resistor, which makes it suitable for a variety of power supply applications. With this voltage regulator, it is possible to precisely regulate larger output current up to 1A.

The working principle of TPS73HD318PWP is based on the use of a voltage divider feedback control loop. The voltage divider is used to detect the output voltage and feed that back to the input of the regulator. The feedback control loop uses the difference between the reference voltage and the divided output voltage to adjust the output voltage of the regulator. This regulation helps to maintain an output voltage that is constant regardless of changes in load current.

TPS73HD318PWP is a low-noise linear voltage regulator, suitable for use in automotive, industrial, and other applications. It is also used in applications such as power noise filtering and power supply sequencing, due to its good EMI performance. The device has a low ripple output and a wide range of operating temperatures, making it suitable for high-efficiency operation.

Due to its high accuracy output voltage, wide voltage range, high efficiency, and low noise characteristics, TPS73HD318PWP is a suitable choice for the widest range of applications requiring low-voltage power supply. It offers advanced features such as overvoltage protection and current limiting, making it ideal for portable devices, automotive, and industrial applications.
