Today, there exists a great variety of voltage regulator products in the current market due to its high demand among electronic devices. This article aims to introduce one of the most popular voltage regulators which is TPPM0301DR. Specifically, this article will discuss its application field and working principle.

Application Field

TPPM0301DR is a three-terminal low-dropout linear regulator with variable voltage output. It is mainly used in applications such as adjustable power supplies, battery chargers, communication systems, instrumentation, portable and mobile products.

This voltage regulator is capable to provide high current output and it is able to work with wide input voltage of 2V to 18V. It also has temperature protection and overload protection features to protect the vocation from over consumption. In addition, this device is used in automotive electronics and it should be able to work under extreme temperatures of -40°C to 125°C.

Working Principle

TPPM0301DR is a positive voltage regulator with an adjustable output voltage. It is mainly composed of three parts, including a reference part, an error amplifier, and an output control stage. The reference part provides a stable output voltage while the error amplifier is used to compare the output voltage with the voltage reference. The output control stage provides a high current to the output terminal.

Due to the low dropout voltage, the output voltage can be maintained at a constant level even when the input voltage varies. Moreover, the wide output voltage range can adjust the output voltage in the range of 1.25V to 18V. In addition, there is also a current limit circuit which provides current protection when the load current exceeds the specified upper limit.

In conclusion, TPPM0301DR is a versatile and highly efficient three-terminal low-dropout linear regulator. It can provide high current output and work with wide input voltage over a wide temperature range. It is primarily used in adjustable power supplies, battery chargers, communication systems, instrumentation, and other electronic applications. The working principle of TPPM0301DR can be further discussed in the light of its reference part, error amplifier, and its output control stage.
