The device has an integrated precision reference and an adjustable current limit. It also features high accuracy over its entire operating temperature range. It has an adjustable current limit with a range of 0 to 500mA and a low quiescent current of 2.5mA. The device also features an adjustable thermal protection limit.

TPS71933-28DRVRG4 is ideal for applications such as mobile phones, wearable devices, and portable medical devices. It can be used to regulate the voltage of small power consumption circuits and is also suitable for input or output polarity protection applications. It is also applicable to low dropout voltage when the voltage is close to the normal operating voltage.

The working principle of this device is based on the control theory. It uses a precision reference to set the regulator’s output voltage. The device senses the output voltage with an error amplifier and compares it to the reference voltage. The output from the error amplifier is used to control the gate of a pass transistor. The higher the voltage at the gate of the transistor, the more current passes through it, thus increasing the output voltage. By controlling the gate voltage, the output voltage can be regulated and maintained at a set level.

The TPS71933-28DRVRG4 is a versatile and efficient linear voltage regulator. Its wide input and output voltage range and its adjustable current limit make it suitable for a variety of applications. Its low quiescent current makes it ideal for battery powered applications. Its integrated precision reference and error amplifier allow for precise voltage regulation and stable output voltage. Its adjustable thermal protection limit ensures that the device is protected from overheating and malfunctions.
