BD25KA5WF-E2 Working Principle

The BD25KA5WF-E2 is a linear voltage regulator with an adjustable output voltage that operates according to the basic principles of a linear regulator. Linear regulators achieve regulation by dissipating excess power in the form of heat, allowing them to supply regulated voltage to the load with low noise and in high-efficiency operation.

The BD25KA5WF-E2’s regulating circuit uses an external resistor to set the desired output voltage. The Reference Voltage, output voltage, and load current are sensed and compared against a reference voltage. The sensed error voltage is then amplified and used to control the power transistor, which regulates the output voltage. This allows the regulator to maintain an accurate output voltage regardless of changes in input voltage, load current, output voltage and temperature.

The BD25KA5WF-E2 is designed with a variety of protection features such as Current Limiting, Overvoltage Protection, Thermal Shutdown and Short circuit current limiting, allowing it to protect the regulator from damage due to overloading or short circuiting.
