The BD30KA5WFP-E2 is a linear programmable voltage regulator with adjustable down output voltage, over-voltage protection, and wide temperature operating range, making it suited for a variety of applications.

The BD30KA5WFP-E2 consists of a low-dropout linear regulator and an external resistor divider, making it possible to set the output voltage with great accuracy. This linear regulation circuit operates within the 0.89mV voltage drop range, allowing for greatly extended battery life. The over-voltage protection circuit protects the device from input voltage fluctaions, and its wide operating temperature range from -40°C to 125°C ensures reliable performance in any environment.

The BD30KA5WFP-E2 is also equipped with an overcurrent protection circuit, as well as other features such as short-circuit protection, reverse current blocking, and a low-power standby mode, making it ideal for use in portable devices.

In addition, the BD30KA5WFP-E2 is designed to be used in a wide range of applications, including medical, automotive, consumer electronics, and industrial applications, making it a versatile and robust power management solution.

The BD30KA5WFP-E2’s working principle is based on a linear-regulator circuit with a resistor divider composed of two resistors. The regulator has a fixed reference voltage, which is usually set to 2.5V. The output voltage is determined by the ratio of the two resistors. When the voltage at the input or output is at or above the set reference voltage, the output voltage will be the same as the reference voltage.

When a load is applied, the output voltage will drop until it reaches the output voltage set by the resistor divider. A decrease in the resistor divider ratio increases the output voltage, while an increase will lower the voltage. The input voltage must remain above the output voltage in order for the regulator to work correctly.

The BD30KA5WFP-E2 also has an internal over-voltage protection circuit that disables the output voltage when the input voltage exceeds the reference voltage. The over-voltage protection circuit is designed to protect the device from input voltage fluctations.

The BD30KA5WFP-E2 is a versatile and robust linear voltage regulator, making it well-suited for a variety of applications. Its adjustable down output voltage, over-voltage protection, and wide temperature operating range make it an ideal choice for power management solutions.
