The onsemi NCP139AFCT100T2G is a precision 1A LDO regulator with a fixed 1.0V output. It features an ultra-low 50µA quiescent current, making it exceptionally well-suited for battery-powered and energy-harvesting applications. With 85dB PSRR and a tiny 6-WLCSP package, it delivers clean, stable power in the most space-constrained designs.
- Ultra-Low Quiescent Current (50µA): Maximizes battery life in portable and standby applications.
- High PSRR (85dB @ 1kHz): Provides excellent noise filtering for sensitive low-voltage digital and analog circuits.
- 1A Output Capability: Supports high transient loads while maintaining stable 1.0V output.
- Miniature 6-WLCSP Package: Enables ultra-compact PCB designs for wearables and IoT modules.
Low-Power IoT Nodes
The 50µA quiescent current significantly extends battery life in always-on IoT sensors, while the 1A peak current handles intermittent radio bursts.
Microcontroller Core Supply
Modern MCUs with 1.0V cores benefit from the tight regulation and low dropout, ensuring reliable operation from a 1.5V or 2.5V input rail.
Energy Harvesting Systems
In energy harvesting, efficiency is paramount. The ultra-low quiescent current minimizes wasted power, making this LDO suitable for solar or thermal harvesting modules.
Wearable Health Monitors
The compact WLCSP package and low power consumption make it perfect for continuous health monitoring devices that run on small coin cells.
Portable Audio Players
High PSRR (85dB) ensures that the 1.0V rail for DSPs remains clean, preventing audible noise in portable audio processing chains.
Smart Home Sensors
For battery-operated smart sensors, the combination of low quiescent current and high current capability provides both long standby time and reliable active performance.
