Powering Your Designs with the ADP1753ACPZ-R7 Low-Dropout Regulator

The ADP1753ACPZ-R7 is a high-performance, low-dropout (LDO) linear regulator from Analog Devices, designed to deliver ultra-low noise, high accuracy, and excellent power supply rejection ratio (PSRR). This compact, 3 A output current LDO is ideal for a wide range of applications, including FPGA power supplies, RF systems, medical devices, and portable electronics.

Key Features of the ADP1753ACPZ-R7

1. High Efficiency & Low Dropout Voltage

The ADP1753ACPZ-R7 operates with a dropout voltage as low as 110 mV at 3 A, ensuring efficient power delivery even when the input voltage is close to the output voltage. This makes it perfect for battery-powered devices where energy conservation is critical.

2. Ultra-Low Noise Performance

With output noise as low as 30 μV RMS, this LDO is optimized for noise-sensitive applications such as RF transceivers and high-speed ADCs/DACs. Its high PSRR (75 dB at 10 kHz) further enhances performance in demanding environments.

3. Flexible Adjustable & Fixed Output Options

The ADP1753ACPZ-R7 supports both adjustable (0.8 V to 3.3 V) and fixed output voltage versions, providing design flexibility. The adjustable version allows engineers to fine-tune the output for specific requirements.

4. Robust Protection Features

Built-in overcurrent protection (OCP), thermal shutdown, and reverse current blocking ensure reliable operation under fault conditions, extending the lifespan of connected components.

Applications of the ADP1753ACPZ-R7

- FPGA & Processor Power Supplies: Ensures stable voltage delivery to high-performance computing systems.

- Wireless Communication Systems: Minimizes noise in 5G base stations and IoT modules.
