Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS7B8650BQDDARQ1 is a low dropout linear regulator dedicated to connecting batteries in automotive applications. With an input voltage range of up to 40V, the device is designed to withstand the transients that can occur in automotive systems, such as sudden load drops. With a quiescent current of only 17µA at light loads, the device is an excellent solution for powering normally-open devices such as microcontrollers (MCUs) and controller area network (CAN) transceivers in backup systems.

The device's advanced transient response allows the outputs to respond quickly to load or line changes, such as during cold-start conditions. In addition, the device's novel architecture minimizes output overshoot during recovery from voltage dips. During normal operation, the device maintains ±0.85% DC accuracy over the entire line, load, and temperature range.

The power supply normal state indication delay can be adjusted through an external component, so the delay time can be configured to suit the application-specific system.

The device is packaged in a thermally conductive package so that heat can be efficiently transferred to the circuit board.

• 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?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
