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.
RF Transceivers
Low noise and fast transient response support clean supply for RF modules, reducing spurious emissions in 2.4GHz applications.
Industrial Control Modules
Wide operating temperature and 150mA capability power logic ICs in factory automation sensors and actuators.
Audio Codec Supplies
Low dropout at 150mA maintains 3.3V rail even with battery sag, preventing audio clipping in portable speakers.
