회사 블로그 Evaluation Board ADP1764-ADJ-EVALZ, For Demonstrating the Features of the ADP1764 Low VIN, Low Noise, CMOS Linear Regulator

Shenzhen Mingjiada Electronics Co., Ltd. as a service provider specializing in high-end electronic component supply, now officially offers the ADP1764-ADJ-EVALZ linear regulator evaluation board from Analog Devices, Inc. This board is designed to assist customers in efficiently evaluating and developing high-performance power management systems.

Product Core Description: ADP1764-ADJ-EVALZ Evaluation Board

The ADP1764-ADJ-EVALZ evaluation board demonstrates the functionality of the ADP1764 low-VIN, low-noise CMOS linear regulator. The ADP1764-ADJ-EVALZ is an adjustable output voltage evaluation board. Using a single voltage supply, voltmeter, ammeter, and load resistor, it enables simple device measurements of line and load regulation, dropout voltage, and quiescent current.

1. Core Functionality and Design

The evaluation board is built around the ADP1764-ADJ (adjustable output version) chip. Its core design allows users to flexibly set the output voltage over a wide range from 0.5V to 1.5V via an on-board resistor network. The board layout optimizes power paths and grounding, featuring clearly marked test points and input/output terminals for easy connection to power supplies, loads, and measurement instruments. This enables intuitive evaluation of the regulator's key performance metrics under real-world operating conditions.

3. Key Performance Demonstrated (Based on ADP1764 Chip)

Ultra-Low Noise Output: Delivers exceptionally clean power with noise density as low as 5 nV/√Hz at 10kHz and integrated noise of only 2 µVrms from 100Hz to 100kHz, making it ideal for driving sensitive analog circuits such as RF transceivers and precision ADCs/DACs.

High Accuracy and Stability: Maintains output voltage accuracy within ±1.5% across all line, load, and temperature variations, ensuring stable and reliable power delivery to the load.

Excellent Power Supply Rejection Ratio: Achieves typical PSRR of 69 dB at 4A load and 10kHz frequency, effectively filtering ripple interference from upstream power sources.

Ultra-Low Dropout Voltage: Typical dropout voltage is only 47 mV at full 4A load current, contributing to higher efficiency and extended battery life in low-input-voltage systems.

Wide Operating Range: Supports input voltages from 1.10V to 1.98V, delivers up to 4A output current, and operates over a temperature range of -40°C to +125°C, meeting the stringent demands of industrial and automotive applications.

Comprehensive Protection: Built-in overcurrent protection, thermal shutdown, and short-circuit protection ensure safe and reliable system operation.
