In an era marked by the deployment of 5G base stations, explosive growth in data center computing power, and high-speed communication in industrial switches, the performance of power management chips directly determines system reliability, energy efficiency, and lifecycle costs.
Awinic Electronics' AW37023 Low-Dropout Linear Regulator (LDO) leverages core advantages such as 3A high current, ±1% full-temperature full-load output accuracy, 5μVrms ultra-low noise, and excellent transient response to deliver stable, efficient, and reliable power solutions for 5G base stations, data centers, industrial internet, and other scenarios, serving as an "invisible guardian" for high-reliability infrastructure.
Product Advantages
01
3A High Current for Easy Handling of High-Load Scenarios
Core components in servers, base stations, and switches have growing current demands. The AW37023QNR supports a continuous 3A output current, stably driving controllers, high-speed FPGAs, and high-power communication modules. Additionally, its NMOS architecture enables ultra-low dropout voltage under high current, with a dropout of only 120mV at full load, significantly reducing heat generation and improving system energy efficiency.
02
5μVrms Ultra-Low Noise to Safeguard Signal Integrity
In noise-sensitive applications such as 5G base station RF front-ends and switch serial decoding links, power supply noise can directly translate into signal interference. The AW37023QNR’s ultra-low noise technology achieves 5μVrms (10Hz-100kHz, 0.8V/3A) performance, ensuring ADC sampling accuracy, PLL clock stability, and bit error rate (BER) metrics for high-speed serial links.
03
±1% Full-Temperature Range Accuracy to Ensure System Reliability
Temperature fluctuations, load changes, and input voltage disturbances are three major challenges to power supply accuracy. The AW37023QNR integrates a high-precision reference voltage source and low-temperature-drift precision resistors, achieving ±1% output accuracy across the full temperature range of -40℃ to 125℃. Its excellent load transient response quickly adjusts for voltage drops, preventing system resets or data errors caused by power fluctuations.
