The BU27TD2WNVX-TL is a Linear Voltage Regulator that belongs to the family of PMIC (power management integrated circuits). It is a positive-voltage regulator designed to provide output voltages of 2.7V to 20V, making it a versatile power source for a wide range of applications. It features a wide operating temperature range of -40°C to +125°C, dedicated enable at shutdown, temperature-compensated reference voltage output, thermal regulation, and built-in protection from reverse polarity and short-circuit faults. Additionally, it is optimized for power-supply performance and requires minimal external components for applications such as motor drives, relays, circuit protection, and more.

The BU27TD2WNVX-TL is built on a low-saturation buck-regulator architecture with a buck converter integrated with a linear post-regulator. This architecture helps makes the device more efficient and less noisy than traditional linear regulators and allows for more precise voltage regulation at higher currents. The device is capable of providing up to 1.3A of output current, although the maximum recommended continuous output current is limited to 1A. It also features an adjustable output voltage, with an adjustable voltage range of 2.7V to 20V.

The BU27TD2WNVX-TL works as follows: the buck converter uses a pair of power MOSFETs (metal-oxide semiconductor field-effect transistors) to step down the voltage, while the post-regulator is used to regulate the voltage. The post-regulator is a linear regulator, meaning the output voltage is kept constant, while the input voltage may vary due to line or load conditions. The linear regulator consists of an error amplifier, a power transistor, and passive components. The error amplifier compares the output voltage with a reference voltage and drives the power transistor to regulate the output. This allows for precise voltage control and a stable output voltage over a wide range of loads and line conditions.

The BU27TD2WNVX-TL can be used in a wide range of applications, including motor drives, relays, circuit protection, and more. Its low noise performance and low dropout voltage make it an ideal choice for these applications. Additionally, it has thermal and current-overload protection features, making it a safe, reliable power source in challenging environments. The wide operating temperature range of -40°C to +125°C ensures reliable operation, even in extreme temperatures.

The BU27TD2WNVX-TL is an efficient, reliable, and versatile linear voltage regulator that is ideal for a wide range of industrial applications. Its wide operating temperature range, low dropout voltage, and high current capacity make it a reliable power source in challenging environments. Additionally, its integrated protection features make it a safe power source, even in extreme temperatures. The wide adjustable voltage range of 2.7V–20V and low noise performance make it an ideal choice for motor drives, relays, circuit protection, and more.
