The Torex XC6221A3127R-G is a high-performance 200mA LDO linear regulator delivering a fixed 3.1V output. Its ultra-low 50µA quiescent current and 70dB PSRR make it an excellent choice for battery-powered and noise-sensitive applications. Housed in a compact 4-USPN package, it offers a minimal footprint without compromising on efficiency or stability.
- Extended Battery Life: Ultra-low 50µA quiescent current minimizes standby power draw, ideal for portable electronics.
- Clean Power Delivery: 70dB PSRR at 1kHz suppresses supply noise, ensuring stable operation for sensitive analog circuits.
- Space-Saving Design: The 4-USPN (0.90x1.2) package is among the smallest available, perfect for compact PCB layouts.
- High Efficiency at Low Dropout: A dropout voltage of just 0.14V at 100mA allows operation close to the output voltage, reducing power loss.
Portable Battery-Powered Devices
With a low quiescent current of 50µA and a 200mA output, this LDO is ideal for extending battery life in wearables, hearing aids, and remote sensors where every microamp matters.
Noise-Sensitive Analog Circuits
The 70dB PSRR at 1kHz effectively filters power supply ripple, making it suitable for powering precision op-amps, ADCs, and audio codecs in portable instrumentation.
Compact IoT Modules
The 4-USPN (0.90x1.2) package saves critical board space in space-constrained IoT nodes, smart tags, and wireless modules while providing a stable 3.1V rail.
Low-Power Microcontrollers
Supply a clean 3.1V to MCUs and SoCs in standby or active mode. The low dropout of 0.14V at 100mA ensures efficient operation even with a near-depleted battery.
Wearable Health Monitors
Its small footprint and stable output make it perfect for continuous glucose monitors, fitness trackers, and ECG patches that require reliable, low-noise power in a tiny form factor.
Reference Voltage Buffering
Use it to buffer a reference voltage for sensor bridges or DACs, leveraging the high PSRR to maintain accuracy in noisy industrial or automotive environments.
