The XC6221A312GR-G from Torex Semiconductor is a high-performance fixed 3.1V LDO regulator designed for ultra-portable applications. It delivers up to 200mA with an exceptionally low quiescent current of just 50 µA, making it ideal for battery-powered devices. The low dropout voltage of 0.14V at 100mA ensures efficient operation. With 70dB PSRR at 1kHz, it provides clean, stable power for noise-sensitive circuits. Its ultra-compact 4-USP (1.2x1.6mm) package is perfect for space-constrained designs.
- Ultra-Low Quiescent Current: 50 µA extends battery life in always-on IoT and wearable devices.
- Low Dropout Voltage: 0.14V at 100mA allows operation close to battery end-of-life.
- High Ripple Rejection: 70dB at 1kHz ensures clean power for RF and audio circuits.
- Ultra-Compact Package: 4-USP (1.2x1.6mm) saves critical board space in miniaturized products.
Wearable Health Monitors
The 50 µA quiescent current and 200mA output are perfect for powering Bluetooth SoCs and sensor hubs in smartwatches and fitness bands, maximizing battery life.
IoT Sensor Nodes
For always-on environmental sensors, the ultra-low dropout of 0.14V at 100mA ensures stable operation even as the battery voltage depletes.
Portable Audio Players
The 70dB PSRR at 1kHz effectively suppresses digital noise from the processor, delivering clean power to audio DACs and headphone amplifiers.
Wireless Earbuds
The tiny 1.2x1.6mm package fits into space-constrained earbud designs while providing stable 3.1V to the RF transceiver and audio codec.
