The ETEK ET63125YB is an ultra-low quiescent current LDO linear regulator delivering a fixed 2.5V output. With a 900 nA ground current and 150mA output capability, it is engineered for battery-powered and energy-harvesting applications. The 0.28V dropout at full load ensures efficient use of input voltage. Housed in a 4-DFN (1x1mm) package, it offers a compact solution for space-constrained designs.
- Extended Battery Life: 900 nA quiescent current minimizes standby drain, ideal for always-on devices.
- Compact Footprint: 4-DFN (1x1mm) package saves PCB space for wearables and IoT modules.
- Low Dropout: 0.28V dropout at 150mA allows operation from nearly depleted batteries.
- Stable Output: 45dB PSRR at 1kHz filters supply noise for sensitive analog circuits.
Battery-Powered IoT Sensors
The 900 nA quiescent current extends battery life in always-on sensor nodes, while the 2.5V output suits low-power MCUs and RF transceivers.
Wearable Health Monitors
The tiny 4-DFN (1x1mm) package fits space-constrained wearables. The 150mA capacity powers optical heart-rate sensors and Bluetooth LE modules.
Portable Medical Devices
Stable 2.5V rail with 45dB PSRR at 1kHz reduces noise coupling from switching converters, ensuring accurate readings in glucose meters and thermometers.
Energy Harvesting Systems
With only 0.28V dropout at 150mA, the regulator maximizes usable voltage from low-voltage harvesters like solar cells or TEGs.
Smart Home Controllers
Powers Zigbee/Thread modules from a 3.0V coin cell, maintaining regulation down to 2.78V, extending operational life.
Industrial Wireless Probes
Low quiescent current and small footprint enable compact, long-life wireless vibration or temperature probes in industrial settings.
