The ET5H133Y from ETEK Microelectronics is a low dropout linear regulator offering a fixed 3.3V output. With a maximum output current of 150mA and an ultra-low quiescent current of 3 µA, this LDO is engineered for power-sensitive applications. The compact 4-DFN (1x1) package allows for integration into space-constrained designs. Featuring a dropout voltage of just 0.95V at full load, it maintains regulation even with low input voltages, making it an excellent choice for battery-operated devices.
- Ultra-Low Power Consumption: 3 µA quiescent current significantly extends battery life in standby and active modes.
- Miniature Footprint: The 4-DFN (1x1) package is ideal for miniaturized electronic designs.
- Low Dropout Performance: 0.95V dropout at 150mA allows operation from nearly depleted batteries.
- Stable 3.3V Rail: Provides a reliable power supply for standard logic and mixed-signal circuits.
Low-Power Microcontrollers
The 3.3V output is the standard logic level for many MCUs. The 150mA current capability is sufficient for most MCU + peripheral combinations.
Wireless Sensor Networks
With only 3 µA quiescent current, this LDO is perfect for battery-powered sensor nodes that need to operate for years on a single coin cell.
Portable Consumer Electronics
The tiny 4-DFN package and low dropout voltage make it suitable for earbuds, fitness trackers, and other compact devices.
Reference Voltage Source
The stable 3.3V output can serve as a reference for ADC circuits or analog comparators in measurement systems.
Smart Home Devices
Ideal for powering sensors and controllers in smart thermostats, door locks, and lighting systems where low standby power is critical.
Industrial Control Modules
Provides a clean 3.3V rail for logic circuits in industrial sensors and actuators, with low dropout ensuring operation from 3.3V battery packs.
