The TPS767D301PWPRG4 is a Positive Voltage regulator that belongs to the family of Linear Voltage Regulators (also called PMIC - Voltage Regulators - Linear). It is a single output device, capable of delivering up to 1A of current. The output voltage is preset at 3.0V, but can be adjusted via the on-board trimming capability. The device also includes a low dropout design, thermal shutdown mode and current limit protection.

This device is typically used in wide range of applications such as wireless charging, portable battery powered systems, PDAs, digital cameras and gaming devices. Its thermal shutdown feature makes it well suited for applications that require a high power output. Additionally, its low dropout feature allows for a lower dropout than other regulators, which is advantageous for extended battery life.

When it comes to the working principle of the TPS767D301PWPRG4, the device uses a control loop of a boosting Buck regulator to regulate the output voltage. The device employs a voltage error amplifier which measures the voltage difference between the reference voltage and the actual output voltage. The reference voltage is generated by a band gap reference source. The error amplifier amplifies the detected error and sends a signal to the buck regulator. The regulator responds to this signal by increasing or decreasing the output voltage until it is equal to the reference voltage.

The TPS767D301PWPRG4 features a shutdown mode that can be activated by external control. In shutdown mode, the device will reduce the output current to zero, allowing for improved power savings. Additionally, it has a current limit feature that will protect the device against excessive current draw or a short circuit. This allows the device to be used in a variety of applications without fear of damage.

Overall, the TPS767D301PWPRG4 is a robust, high-performance positive voltage regulator built on a low dropout design. It is capable of delivering up to 1A of current with an output voltage that can be adjusted via the on-board trimming capability. The device includes a wide range of safety features such as shutdown mode and current limit protection, making it suitable for a variety of applications. Its low dropout feature allows for improved battery life, making it a great choice for use in portable applications.
