BU1CTD3WG-TR Application Field and Working Principle

The BU1CTD3WG-TR is a three-terminal adjustable voltage regulator designed to drive up to 5A of load current at an output voltage of varying up to 6.8V. It is part of a family of linear regulated power supply products, or PMIC - Voltage Regulators - Linear, that deliver high current over the full temperature range of -40℃ to +125℃. It provides a very simple solution to many power supply problems. Despite its small size, the BU1CTD3WG-TR provides a high absolute accuracy (±1.5%) over the full voltage and temperature range, as well as extremely low dropout voltages. This makes it an ideal solution for powering a wide variety of light-load and/or low/medium voltage applications.

The BU1CTD3WG-TR includes a built-in Zener reference, current limit, and thermal protection. It operates from an input voltage range of 4.5V to 30V on the voltage regulator and has an excellent line/load regulation of 0.2% maximum and output voltage accuracy of ±1.5%. In addition, it is available with a range of output voltage options, including 2.5V, 3.3V, 5V and 6.8V. It is guaranteed to deliver up to 5A of load current with no minimum load.

The BU1CTD3WG-TR works on a standard voltage regulator principle. Current from the input (Vin) is regulated by a circuit voltage divider and/or a reference such as a Zener diode. The current from the divider is then compared to the output voltage, adjusting the output drives the current up or down to match the target voltage. The voltage difference is then used to regulate the current flow, allowing the output voltage to remain constant despite varying load or input voltages. This is the same principle used by series and shunt-type voltage regulators, but the BU1CTD3WG-TR is able to maintain output voltage accuracy and stability over a very wide range of output currents.

The superior stability of the BU1CTD3WG-TR is due to its ability to maintain a minimum dropout voltage over the entire load range and temperature ranges. This dropout voltage is usually defined as the minimum input voltage required to maintain a given output voltage. The BU1CTD3WG-TR is capable of maintaining a low dropout voltage over its entire operating voltage range, providing superior performance over similar devices. This makes it ideal for a wide range of applications requiring a consistently accurate output voltage.

In summary, the BU1CTD3WG-TR is a three-terminal adjustable voltage regulator ideal for high current and low dropout voltage applications. It is capable of delivering up to 5A of current over the full temperature range of -40℃ to +125℃, with excellent line/load regulation and accuracy. Due to its low dropout voltage and excellent stability, the BU1CTD3WG-TR is ideal for a variety of light-load and/or low/medium voltage applications, making it an invaluable addition to the PMIC - Voltage Regulators - Linear category.
