The MIC5255-3.0BD5 is a fixed 3.0V low dropout linear regulator delivering up to 150mA. Its low quiescent current and 0.25V dropout voltage make it suitable for battery-operated equipment. The TSOT-23-5 package offers a compact solution for space-constrained designs.
- Low quiescent current (150µA) extends battery life in portable applications.
- Low dropout voltage (0.25V @ 150mA) maintains regulation with minimal headroom.
- Good PSRR (60dB~50dB) reduces supply noise for sensitive loads.
- Compact TSOT-23-5 package saves PCB space.
Battery-Powered Portable Devices
The low 150µA quiescent current and 0.25V dropout at 150mA make it ideal for extending battery life in handheld electronics like remote controls and wearables.
