Among the features of this device, it is capable of regulating the DC and AC voltage outputs, handling high voltage input and operating over a wide temperature range. As such, this IC is suitable for a variety of applications, from home appliances and industrial components to automotive electronics.

In terms of its basic physical characteristics, this device is in an 8-lead package, with a maximum current rating of 7.5A and a maximum voltage rating of 23V. The maximum junction temperature is 230°C and the price of the IC ranges between 40 and 45 US Dollars. Its power dissipation capabilities are rated at 203 milliwatts.

The BD3941HFP-TR Linear Voltage Regulator is a customizable 3-terminal device which allows fairly accurate regulation of an input voltage. It can be used with a wide range of input voltages, making it a very versatile component. This regulator has three main components including ground, power input and a reference voltage output. A voltage divider adjusts the reference voltage output to the actual desired voltage. The output voltage can be further customized by the user with a single resistor.

The regulator’s basic operating principle involves two stages. The first stage is referred to as the error amplifying stage. This stage acts like a comparator, taking the difference between the reference voltage and the input voltage. If the mismatch between the two is positive, then the error amplifier will raise the output voltage until it equals the reference voltage. The second stage is the power stage which amplifies the error signal and provides the power to regulate the output voltage. This stage also allows the device to operate in both AC and DC power.

BD3941HFP-TR provides improved accuracy over a wide temperature range with a voltage reference accuracy of +/-1%. It has over-current protection, input and output overvoltage protection and open circuit protection. It is Pb-free and compliant with the EU Directive 2002/95/EC.
