The ET63328YB from ETEK Microelectronics is a fixed 2.8V ultra-low quiescent current LDO regulator. It delivers up to 300mA with a low dropout voltage of 0.5V at full load. The standout feature is its incredibly low quiescent current of just 900 nA, making it one of the most power-efficient regulators in its class. Packaged in a miniature 4-DFN (1x1mm) package, it is designed for space-constrained, battery-powered applications where every microamp matters.
- Ultra-Low Quiescent Current (900 nA): Extends battery life in always-on and standby applications, ideal for IoT and wearables.
- High Output Current (300mA): Supports a wide range of loads while maintaining low power consumption.
- Low Dropout (0.5V @ 300mA): Maximizes efficiency by allowing operation from input voltages close to the output.
- Miniature 4-DFN (1x1mm) Package: Enables ultra-compact PCB designs for next-generation portable devices.
Ultra-Low Power Wireless Modules
With a quiescent current of just 900 nA, this LDO is perfect for Zigbee, LoRa, and other low-power wireless modules that require minimal standby current.
Wearable Health Monitors
The tiny 1x1mm DFN package and low dropout make it ideal for compact wearables like smart patches and continuous glucose monitors.
Battery-Powered Sensors
