Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADP7156ACPZ-3.3 is a linear voltage regulator that is powered by a 2.3V to 5.5V supply and has a maximum output current of 1.2A. The ADP7156ACPZ-3.3 adopts an advanced proprietary architecture, offering high power supply suppression and ultra-low noise characteristics. It only requires a 10 μF ceramic output capacitor to achieve outstanding line and load transient response performance. This device has the following core characteristics and parameters:

Input voltage range: 2.3V to 5.5V

It can provide 16 standard voltages ranging from 1.2V to 3.3V

Maximum load current: 1.2A

Low noise

Total integral noise from 100 Hz to 100 kHz: 0.9 µV rms

Total integral noise from 10 Hz to 100 kHz: 1.6 µV rms

Noise spectral density: 1.7 nV/√Hz (10 kHz to 1 MHz)

Power Supply Rejection Ratio (PSRR

80 dB (1 kHz to 100 kHz); 60 dB (1 MHz), VOUT = 3.3 V, VIN = 4.0 V

Pressure difference: 120 mV (typical value, IOUT = 1.2 A, VOUT = 3.3 V)

Initial accuracy: ±0.6% (when ILOAD = 10 mA)

Initial accuracy across the entire line, load and temperature range: ±1.5%

Static current: IGND = 4.0 mA (no-load), 7 mA (1.2 A)

Low turn-off current: 0.2 μA

Maintain stability by using a 10 µF ceramic output capacitor

Precision enabling

10-pin 3mm x 3mm LFCSP package

Passed the AEC-Q100 automotive application certification

Typical applications

Adapted to noise-sensitive applications: phase-locked loop (PLL), voltage-controlled oscillator (VCO), and PLL with integrated VCO

Communication and infrastructure

Return route and microwave link

• 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.
