Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS7A2650DRVR low dropout (LDO) linear regulator supports a 2.4V to 18V input voltage range and features extremely low quiescent current (IQ). These features better enable modern appliances to meet increasingly demanding energy requirements and help extend the battery life of portable power solutions.

The TPS7A2650DRVR is available in both fixed-voltage and adjustable-voltage versions. For greater flexibility or higher output voltage, the adjustable voltage version uses a feedback resistor to set the output voltage from 1.24 V to 17.4 V. Both versions feature a 1% output regulation accuracy for precision adjustment of the microcontroller (MCU) reference voltage.

With an open-drain power-good state (PG) output, the device can provide reset for the MCU, or wire-OR and level-switch with other open-drain PGs to provide system-wide PG or reset.

The TPS7A2650DRVR LDO has a maximum dropout of less than 590mV at 500mA, making it more efficient than standard linear regulators. This maximum dropout voltage allows the device to achieve 87.7% efficiency with a 5.0V output voltage (VOUT) from a 5.7V input voltage (VIN).

• 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.
