The MIC5205-2.7BM5 is a fixed 2.7V low-dropout linear regulator from Micrel, delivering up to 150mA in a compact SOT-23-5 package. Its low 150µA quiescent current and 0.35V dropout at full load make it an efficient choice for battery-operated and portable applications. With 75dB PSRR at 100Hz, it provides clean, stable power for sensitive analog and RF circuits.
- Extended Battery Life: Ultra-low 150µA quiescent current minimizes standby power draw.
- Clean Output: 75dB PSRR at 100Hz rejects supply noise for sensitive loads.
- Compact Footprint: SOT-23-5 saves board space in space-constrained designs.
- Low Dropout: 0.35V at 150mA allows operation from nearly depleted batteries.
Battery-Powered Portable Devices
The low 150µA quiescent current and 2.7V fixed output make it ideal for extending battery life in handheld meters, remote controls, and wearable sensors.
Precision Analog Reference Supply
With 75dB PSRR at 100Hz, this LDO effectively filters ripple from switching regulators, providing a clean 2.7V rail for op-amps and ADCs.
Wireless Module Power
RF modules (Bluetooth, Zigbee) require stable low-noise supply; the MIC5205-2.7BM5 delivers 150mA with minimal voltage droop during transmit bursts.
Automotive Sensor Interfaces
Its SOT-23-5 footprint and thermal performance suit engine control unit sensors needing a regulated 2.7V from a 3.3V or 5V rail.
Portable Audio Equipment
The high PSRR reduces audible hum from digital noise, ensuring clean power for headphone amplifiers and codecs.
Industrial Control Loops
For 4-20mA transmitters, the low dropout ensures regulation even when the loop supply dips, maintaining accuracy.
