BD3508EKN-E2 is a voltage regulator designed for low voltage system, such as TV, BLU-RAY player and other home audiovisual equipment. It is a two terminal, linear, integrated quiescent regulator for use in surface mount applications. It provides a current limit protection, with a maximum output current of 500mA.
Application Field
BD3508EKN-E2 is mainly used in low voltage system, and it is suitable for a variety of home audiovisual products, such as TV, BLU-RAY player and other related equipment. It also applies to a wide variety of other applications, such as advertising machines, smart home products, etc. It can also provide a stable operating voltage, which helps to secure the best working performance of the related products.
Working Principle
BD3508EKN-E2 adopts the two terminal low dropout regulator design and provides a current limitation protection to prevent over-current from damaging the circuit. The device maintains a regulated output voltage with only 8mA drop at 500mA output current. It has an internal p-channel MOSFET with very low on-state resistance for high efficiency operation. Input voltage can range from 2.2V up to 7V and output voltage range from 0.8V to 6.2V.
When the input voltage is greater than or equal to the output voltage, plus a small voltage drop, the internal p-channel MOSFET is open. The lower terminal is providing the output current, while the higher terminal is connected to the input voltage source, allowing the current to flow into the regulator, and then to the load. When the load draws more current, the voltage drop increases, and a feedback loop reduces the output current until it is back in the safe operating range.
When the input voltage is lower than the output voltage, the internal p-channel MOSFET is completely closed, blocking any current to flow from the input to the output. In this situation, the output voltage will be sustained at a constant level, providing a stable operating environment for the related products.
Conclusion
In summary, BD3508EKN-E2 is a linear voltage regulator designed for low voltage system. It provides a current limit protection and its output voltage can range from 0.8V up to 6.2V. It is widely used in various applications, such as home audiovisual equipment, advertising machines, smart home products, etc. It secures the best working performance of the related products and provides a stable environment for them. BD3508EKN-E2 is an excellent choice for applications that require a high efficiency and low dropout linear regulator.
