The Micrel MIC5255-3.0YM5 is a low dropout linear regulator providing a fixed 3.0V output at up to 150mA. Its low 0.25V dropout voltage and 150µA quiescent current make it efficient for battery-powered applications. Housed in a compact SOT-23-5 package, it offers a practical solution for portable and industrial designs requiring clean, regulated power.
- Low Dropout (0.25V @ 150mA): Maximizes efficiency in battery-operated devices by allowing operation closer to the battery's end-of-life voltage.
- Stable 3.0V Output: Provides a precise voltage rail for logic and analog circuits.
- Compact SOT-23-5 Package: Saves board space in space-constrained designs.
- Moderate PSRR (60dB): Offers adequate noise rejection for typical portable applications.
Battery-Powered Portable Devices
The low 0.25V dropout at 150mA allows efficient use of battery voltage, extending runtime in devices like remote controls and portable meters.
Analog Sensor Power
With 60dB PSRR at low frequencies, this LDO provides clean power to analog sensors and op-amps, reducing measurement errors in instrumentation.
Wireless Modules (Zigbee, LoRa)
The 150mA output is sufficient for many low-power wireless transceivers, while the stable 3.0V rail ensures reliable RF performance.
Audio Codec Supplies
For portable audio devices, the 50-60dB PSRR helps suppress power supply hum and noise, improving audio clarity.
Automotive Interior Electronics
The SOT-23-5 package and robust performance make it suitable for non-critical automotive interior modules like dashboard sensors.
Industrial Control Interfaces
Provides a stable 3.0V reference for logic-level interfaces in industrial control systems, ensuring reliable communication.
