Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS7B87-Q1 is a low dropout linear regulator designed for connecting batteries in automotive applications. With an input voltage range of up to 40V, the device can withstand the transients that can occur in automotive systems, such as load drops. With a quiescent current of only 17µA at light load, this device is an excellent solution for powering normally open devices such as microcontrollers (MCUs) and controller area network (CAN) transceivers in backup systems.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
