Linear Voltage Regulators (LVRs) are a type of DC-DC power supply utilizing a continuous output voltage generated at a low switching frequency. Linear voltage regulation is achieved through the electrical series resistance of a rectifier, which acts to maintain the output voltage. The most popular linear regulators are known as "step-down" regulators, meaning they take a higher input voltage, convert it, and output a lower voltage. Examples of this type of regulator include the BU33TD2WNVX-TL.

The BU33TD2WNVX-TL is a three-terminal positive adjustable linear voltage regulator. It can be used in a variety of applications such as automatic equipment, communication, computers, mobile phones, and other DC power supply equipment. It is designed to provide a fixed output voltage of 2.85V with a ±2% accuracy to further improve the cost and reliability of the system. It provides a good balance between dynamic performance and current consumption allowing for a wide operating range. With a wide input voltage range of 4.75V to 18V, and an output current limit of 150mA, the BU33TD2WNVX-TL is ideal for a wide range of applications.

The BU33TD2WNVX-TL has many features which make it an ideal choice for applications requiring low output voltage and high current capabilities. It is protected against short-circuit and over current conditions, so no external current limiting is required. It also provides over-temperature protection and thermal shutdown with a hysteresis of 10°C between 125°C and 135°C. Additionally, the BU33TD2WNVX-TL has an adjustable voltage range of 2.5V to 17V with a reference voltage of 2.85V and offers low quiescent current of 5μA.

The design of the BU33TD2WNVX-TL is optimized for use in battery-powered applications. It incorporates a power-saving EN pin which enables the power supply to be shut down reducing system power consumption. By using a low quiescent current, the BU33TD2WNVX-TL is capable of operating at very low temperatures without consuming excessive power. The BU33TD2WNVX-TL also operates over an extended temperature range from -40°C to +125°C, making it suitable for a wide range of applications.

The BU33TD2WNVX-TL works by taking input voltage and reducing it to a fixed output voltage. This is done by means of a feedback loop which maintains a constant output voltage despite changes in the primary power supply. It utilizes a voltage divider and an error amplifier to precisely set the output voltage by comparing the output voltage to an internal reference. The error amplifier measures any difference between the internal reference and the output voltage and applies corrective feedback to the error amplifier to make needed changes. The resulting output voltage is regulated with a high degree of accuracy.

In addition, the BU33TD2WNVX-TL is designed to minimize power dissipation and output voltage noise. This is done by using a low-impedance winding for the feedback resistor, which results in lower noise and power dissipation. It also utilizes a high-frequency switching output stage, which allows for higher load current capabilities while keeping the noise low.

In summary, the BU33TD2WNVX-TL is an ideal three-terminal linear voltage regulator for a wide range of applications. It offers excellent dynamic performance, low noise and power dissipation, low quiescent current, over-temperature protection and thermal shutdown, and wide operating range. It is designed for use in battery-powered applications and is capable of operating at a wide range of temperatures. And it provides an adjustable output voltage range of 2.5V to 17V with very low output voltage deviation and accuracy. With these features, the BU33TD2WNVX-TL is well suited for a variety of applications requiring low output voltage and high current capabilities.
