The ISL9003AIRUHZ-T from Intersil is a high-performance, low quiescent current LDO linear regulator. It delivers a fixed 2.75V output and is capable of sourcing up to 150mA of load current. With a low dropout voltage of just 0.4V at full load, it maintains a stable output even with a small input-to-output voltage margin. The device's 40 µA quiescent current makes it an excellent choice for battery-operated equipment. Housed in a compact 6-UTDFN package, it is designed for space-constrained applications requiring clean, regulated power.
- Extended Battery Life: The ultra-low 40 µA quiescent current minimizes standby power draw, significantly prolonging battery runtime in portable devices.
- High Efficiency at Low Dropout: A 0.4V dropout at 150mA allows operation from nearly depleted batteries, maximizing usable energy.
- Space-Saving Design: The 6-UTDFN (1.6x1.6) package is ideal for compact PCBs in wearables and IoT modules.
- Stable and Clean Output: As a linear regulator, it provides low output noise and fast transient response, ensuring reliable performance for sensitive electronics.
