The MIC5219-2.7BM5 is a fixed 2.7V low-dropout linear regulator from Micrel, delivering up to 500mA with an ultra-low 8µA quiescent current. Its 0.6V dropout at full load and 75dB PSRR at 120Hz make it ideal for battery-powered and noise-sensitive applications. Housed in a compact SOT-23-5 package, it offers thermal shutdown and current limiting for robust operation.
- Extended Battery Life: 8µA quiescent current minimizes standby drain in portable devices.
- Clean Output: 75dB PSRR at 120Hz rejects mains ripple for sensitive analog circuits.
- High Current Density: 500mA output in SOT-23-5 saves board space without sacrificing performance.
- Low Dropout: 0.6V dropout allows operation from nearly depleted batteries.
Battery-Powered IoT Sensors
The 8µA quiescent current extends battery life in always-on sensor nodes, while the 500mA capability supports periodic radio bursts.
Portable Medical Devices
Low dropout of 0.6V allows operation from a single Li-ion cell down to 3.3V, maintaining stable 2.7V for sensitive analog front-ends.
Automotive ECU Power Rails
With 75dB PSRR at 120Hz, it rejects alternator ripple, providing clean 2.7V for microcontroller and CAN transceiver supplies.
Industrial Control Modules
Wide input range and thermal protection make it suitable for 24V industrial buses stepped down to 2.7V logic rails.
Wearable Fitness Trackers
Small SOT-23-5 footprint and low dropout enable direct regulation from a 3.0V coin cell, maximizing usable capacity.
RF Transceiver Power
High PSRR and fast transient response ensure stable voltage during GSM/GPS transmission bursts, preventing frequency drift.
