The ET63333YB from ETEK Microelectronics is a fixed 3.3V ultra-low quiescent current LDO regulator. It delivers up to 300mA with an impressively low dropout voltage of just 0.45V at full load. With a quiescent current of only 900 nA, it is engineered for battery-powered and energy-efficient applications. The miniature 4-DFN (1x1mm) package makes it an excellent choice for compact, portable devices requiring a stable 3.3V supply.

  • Ultra-Low Quiescent Current (900 nA): Maximizes battery life in always-on IoT and wearable devices.
  • Low Dropout (0.45V @ 300mA): Ensures efficient operation even when the input voltage is close to 3.3V.
  • High Output Current (300mA): Supports a wide range of loads, from sensors to wireless modules.
  • Compact 4-DFN (1x1mm) Package: Ideal for space-constrained designs without compromising performance.
