The ISL9003AIENZ-T is a low dropout linear regulator from Intersil, delivering a fixed 3.3V output with up to 150mA of current. Its ultra-low 40µA quiescent current makes it an excellent choice for battery-operated devices. The 0.325V dropout at full load ensures efficient operation even with low input margins. Housed in a compact SC-70-5 package, this LDO provides stable, clean power for space-constrained applications.
- Extended Battery Life: 40µA quiescent current minimizes standby power draw in portable devices.
- Compact Footprint: SC-70-5 package saves board space for miniaturized designs.
- Low Dropout: 0.325V at 150mA maintains regulation with minimal headroom.
- Stable Output: Fixed 3.3V rail with low noise for sensitive electronics.
Battery-Powered IoT Sensors
The 40µA quiescent current and 150mA output are ideal for always-on sensor nodes, extending battery life in remote monitoring systems.
Portable Medical Devices
Stable 3.3V rail with low dropout ensures reliable operation of sensitive analog front-ends in glucose monitors and pulse oximeters.
Wearable Electronics
The SC-70-5 package (2mm x 2.1mm) fits tight PCB constraints in smartwatches and fitness bands while providing clean power to MCUs.
