The MAX8868EUK28 is a fixed 2.8V low dropout linear regulator from Analog Devices, delivering up to 150mA of output current. It features a low typical dropout voltage of 0.165V at full load and a quiescent current of just 180µA, making it ideal for battery-powered and portable applications. The SOT-23-5 package ensures a compact solution for space-constrained designs.
- Ultra-Low Quiescent Current: 180µA extends battery life in portable and standby applications.
- Low Dropout Voltage: 0.165V at 150mA allows operation with minimal input-to-output headroom.
- Compact SOT-23-5 Package: Saves board space for miniaturized designs.
- Good High-Frequency PSRR: 63dB at 10kHz reduces noise from switching regulators.
Battery-Powered Wearables
The 180µA quiescent current and 0.165V dropout make it ideal for extending battery life in smartwatches and fitness trackers, where a stable 2.8V rail is needed for sensors and MCUs.
Portable Medical Devices
With 63dB PSRR at 10kHz, this LDO provides clean power for glucose monitors and pulse oximeters, reducing noise interference in sensitive measurement circuits.
Bluetooth and IoT Modules
The small SOT-23-5 footprint and low dropout voltage allow direct regulation from a Li-ion cell (3.0-4.2V) to a 2.8V supply for RF transceivers, ensuring reliable wireless communication.
Audio Codec Power Supply
For portable audio players, the low noise and good PSRR characteristics help maintain audio fidelity by providing a clean 2.8V supply to codecs and amplifiers.
Automotive Key Fobs
The low quiescent current is critical for always-on applications like key fobs, where the regulator powers a 2.8V MCU while minimizing battery drain during standby.
