The onsemi NCP551SN15T1G is a fixed 1.5V low dropout linear regulator delivering up to 150mA. Its ultra-low 8 µA quiescent current and 0.22V dropout at 10mA make it ideal for battery-powered and energy-sensitive applications. Housed in a compact 5-TSOP package, it provides a stable, noise-free output for portable electronics, wearables, and IoT devices.
- Extended Battery Life: Ultra-low 8 µA quiescent current minimizes standby power draw, ideal for always-on devices.
- Stable Low-Voltage Output: Fixed 1.5V output with 0.22V dropout at 10mA ensures reliable operation near end-of-battery voltage.
- Compact Footprint: 5-TSOP package saves PCB space for space-constrained wearable and portable designs.
- Sufficient Current Capacity: 150mA output supports MCUs, sensors, and low-power RF modules.
Battery-Powered IoT Sensors
The ultra-low 8 µA quiescent current extends battery life in always-on sensor nodes, while the 150mA output handles periodic wireless transmissions.
Portable Medical Devices
The 1.5V fixed output and low dropout of 0.22V @ 10mA ensure stable operation from a single Li-ion cell or two alkaline batteries, critical for glucose monitors and hearing aids.
Wearable Electronics
Compact 5-TSOP package and low dropout allow direct regulation from a 1.8V rail, ideal for smartwatches and fitness trackers requiring minimal board space.
Microcontroller Power Supplies
Provides clean 1.5V rail for low-power MCUs in industrial control, with 150mA capacity sufficient for core logic and peripheral I/O.
Energy Harvesting Systems
With only 8 µA quiescent draw, it maximizes efficiency in solar or thermal harvesting setups where every microamp of overhead reduces harvested energy available to the load.
