The ET51633YB from ETEK MICROELECTRONICS is a 300mA LDO linear regulator providing a fixed 3.3V output. With a low 70µA quiescent current and 75dB PSRR, it delivers clean, stable power for portable and space-constrained applications. The ultra-compact 4-DFN (1x1) package enables miniaturized designs.
- Miniature Footprint: 1x1mm DFN package saves critical board space.
- Stable 3.3V Rail: 75dB PSRR at 1kHz filters supply noise.
- Low Power Loss: 0.38V dropout at 300mA improves efficiency.
- Battery Friendly: 70µA quiescent current extends standby time.
Compact Sensor Modules
The 1x1mm DFN package and 3.3V output are ideal for miniaturized environmental sensors requiring stable power.
Battery-Powered Remote Controls
70µA quiescent current and 300mA capability support IR/RF remote controls with long standby life.
Portable Audio Players
75dB PSRR at 1kHz ensures clean 3.3V supply for audio DACs, reducing audible noise.
Smart Home Devices
Reliable 3.3V regulation for smart switches, thermostats, and hub controllers with moderate power needs.
Industrial Sensors
Low dropout of 0.38V allows operation from 3.7V Li-ion batteries down to near-empty, extending usable range.
Wearable Health Monitors
Compact footprint and efficient operation suit heart-rate and activity monitors worn continuously.
