The ET53630YB is a fixed 3.0V LDO regulator delivering 300mA in an ultra-compact 4-DFN (1x1mm) package. With an ultra-low dropout of 0.23V at full load and 70µA quiescent current, it maximizes battery life in portable devices. Its excellent PSRR (78dB at 1kHz) ensures clean power for RF and audio circuits. Ideal for wearables, IoT nodes, and medical monitors.
- Ultra-Low Dropout: 0.23V at 300mA enables efficient regulation from 3.3V rails.
- Low Quiescent Current: 70µA quiescent current extends battery life in always-on devices.
- High PSRR: 78dB at 1kHz rejects switching noise for clean RF and audio supplies.
- Miniature Package: 4-DFN (1x1mm) saves PCB space in compact designs.
