Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS78425BQWDRBRQ1 ultra-low dropout regulator (LDO) is a small, low quiescent current LDO that delivers 300mA with excellent line and load transient performance.

With low output noise and excellent PSRR performance, the device is suitable for powering sensitive analogue loads. With an input voltage range of 1.65V to 6.0V and an adjustable output voltage range of 1.2V to 5.5V, the TPS784-Q1 is a flexible post regulator. It also offers a fixed output voltage of 0.65V to 5.0V to power common voltage rails.

The TPS784-Q1 features foldback current limiting to reduce power dissipation during overcurrent conditions, and an EN-side input helps meet the system's power supply timing requirements. Internal soft-start reduces inrush current by controlling the startup process, thereby reducing the input capacitance used.

The TPS784-Q1 provides an active pull-down circuit that allows the output load to discharge quickly when disabled.

• 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.
