The ISL9003AIEJZ-T is a fixed 2.8V LDO regulator from Intersil, capable of delivering 150mA. Its 40µA quiescent current is ideal for battery-powered and energy-harvesting applications. With a dropout of 0.4V at full load, it maintains regulation with minimal input overhead. The SC-70-5 package offers a compact solution for space-limited designs requiring a stable low-voltage rail.
- Ultra-Low Power: 40µA quiescent current extends battery life in standby modes.
- Low Dropout: 0.4V at 150mA supports low input voltages.
- Compact SC-70-5: Small footprint for portable and wearable devices.
- Fixed 2.8V Output: Simplifies design with no external resistor divider.
