BD7802FP-E2 application field and working principle

BD7802FP-E2, or better known as BOMBAY7802FP, is a linear voltage regulator produced by Olimex. It is commonly utilized in a multitude of power management applications, particularly in the automotive, medical, and lighting industries. This linear voltage regulator is designed for medium current outputs and is capable of regulating a wide range of voltages via an integrated, adjustable reference. It\'s a popular choice for battery- and switched-mode power supply applications that require efficient energy usage.

The two primary components of a linear voltage regulator are the input and output blocks, which form the basis of its functionality. The input is the power source, which can be either a rectified AC voltage or a DC voltage. The output is an adjustable lower DC voltage, typically limited to around 10V. The voltage regulator rectifies the AC current and then transforms it into the targeted DC voltage. The adjustable reference sets the exact output voltage that the regulator is to maintain.

The BD7802FP-E2 features an unusually wide input voltage range between 8V and 45V. The output voltage range is between 1.2V and 28V, while the output current is adjustable up to 4A. Furthermore, the device provides over-voltage protection and under-voltage protection without requiring any external components. This makes it an excellent option for power boards and telecom power systems.

Aside from its adjustable reference, the BD7802FP-E2 also boasts a variety of other features that make it especially attractive to power management engineers. First of all, its efficiency is quite remarkable and often exceeds 80%. This is due to the unique multi-stage design that eliminates much of the power dissipation that often occurs in linear voltage regulators. The device\'s small footprint size also makes it especially appealing, especially in applications that have limited space requirements. Finally, it offers internal thermal protection and current limiting protection, which can be adjusted via an external resistor.

The BD7802FP-E2 is an outstanding example of a linear voltage regulator that can offer reliable and efficient power output in a variety of applications. Its wide input voltage range, adjustable output voltage, low cost, and small size make it particularly attractive for automotive, medical, and lighting applications. Moreover, its internal protection and efficient energy usage make it an ideal choice for cost-sensitive and space-constrained solutions.
