Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS7A8500RGRR is a low-noise (4.4 µVRMS), low-dropout (LDO) linear regulator with a 4A pull-current capability and a maximum dropout voltage of only 240mV. The output voltage of this device can be programmed via pins within a range of 0.8V to 3.95V and can be adjusted via an external resistor divider within a range of 0.8V to 5.0V.

The TPS7A8500RGRR combines low noise (4.4 µVRMS), high power supply rejection ratio (PSRR), and high output current performance, making it ideal for high-speed communication, video, medical, or test and measurement applications, capable of driving up to 1A load current. The high performance of the TPS7A85 effectively limits phase noise and clock jitter generated by the power supply, making it ideal for powering high-performance serialisers and deserialisers (SerDes), analogue-to-digital converters (ADCs), digital-to-analogue converters (DACs), and radio frequency (RF) components. RF amplifiers particularly benefit from the device's high performance and 5.0V output capability.

Test and measurement

• 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.
