The Torex XC6220A381PR-G is a fixed-output LDO linear regulator providing 3.8V at up to 1A. Its low 18 μA quiescent current and 0.655V dropout at full load make it ideal for power-sensitive applications. The SOT-89-5 package offers a compact footprint with good thermal dissipation. With 50dB PSRR at 1kHz, it provides clean, stable power for noise-sensitive electronics.
- Extended Battery Life: Ultra-low 18 μA quiescent current minimizes standby drain in portable devices.
- High Current Capacity: 1A output supports demanding loads while maintaining regulation.
- Low Dropout: 0.655V dropout at 1A allows operation from marginally higher input voltages, improving efficiency.
- Noise Rejection: 50dB PSRR at 1kHz filters supply ripple for clean output.
Smart Home Hubs
The 3.8V output and 1A capability power multiple sensors and communication modules simultaneously, while low quiescent current keeps idle power minimal.
Wearable Fitness Trackers
With 18 μA quiescent current, this LDO extends battery life between charges, and the SOT-89-5 package fits compact PCB layouts.
Embedded Computing
For single-board computers, the low dropout ensures stable 3.8V even when input from a battery sags under load, preventing system crashes.
Telecom Base Stations
The 50dB PSRR at 1kHz rejects interference from adjacent RF circuits, ensuring clean power for signal processing ICs.
LED Lighting Controllers
This regulator provides a stable 3.8V rail for PWM controllers and logic, with 1A capacity to drive auxiliary circuits.
Test and Measurement Equipment
Precision instruments benefit from the low noise and stable output, maintaining measurement accuracy over temperature and load variations.
