Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

ADP1764ACPZ1.25 is a low noise, low dropout (LDO) linear regulator. It is designed to operate from a single input supply with an input voltage as low as 1.10 V without the requirement of an external bias supply to increase efficiency and provide up to 4 A of output current (IOUT).

Product Features

4A maximum output current

Low input voltage supply range

VIN = 1.10V to 1.98V, no external bias supply required

Fixed output voltage range (VOUT_FIXED): 0.55V to 1.5V

Adjustable output voltage range (VOUT_ADJ): 0.5V to 1.5V

Ultralow noise: 2μV rms, 100Hz to 100kHz

Noise spectral density: 5nV/√Hz at 10kHz; 4nV/√Hz at 100kHz

Low dropout voltage: 47mV typical at 4A load

Operating supply current: 5mA typical at no load

±1.5% fixed output voltage accuracy over line, load, and temperature

Excellent power supply rejection ratio (PSRR) performance

69dB typical at 10 kHz at 4A load

46dB typical at 100 kHz at 4A load

Excellent load/line transient response

Soft start to reduce inrush current

• 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.
