Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS79333DBVRQ1 low dropout (LDO) low power linear regulator features a high power supply rejection ratio (PSRR), ultra-low noise, fast start-up, and excellent line and load transient response in a small out-of-line SOT-23 package.

Each TPS793-Q1 device in the series is stable and has a small 2.2 µF ceramic capacitor at the output. the TPS793xx-Q1 series uses an advanced proprietary BiCMOS manufacturing process to produce extremely low dropout voltages (e.g., 112 mV at 200 mA for the TPS79330-Q1). Each device achieves a fast start-up time (approximately 50 µs with a 0.001 µF bypass capacitor) while consuming extremely low quiescent current (170 µA typical). In addition, when the device is placed in standby mode, the supply current drops below 1 µA. The TPS79328-Q1 exhibits an output voltage noise of approximately 32 µVRMS when using a 0.1 µF bypass capacitor. Applications employing noise-sensitive analog components, such as portable RF electronics, will benefit from the high PSRR and low noise characteristics, as well as the fast response time.

• 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.
