The MAX8878EUK30 is a low dropout linear regulator providing a fixed 3.0V output at up to 150mA. With a typical dropout of 165mV and quiescent current of 180µA, it is designed for power-sensitive portable applications. The SOT-23-5 package enables compact PCB layouts.

  • Efficient Power Management: 180µA quiescent current reduces idle power consumption.
  • Low Dropout: 165mV dropout allows operation with small input-to-output voltage margins.
  • Space-Saving: SOT-23-5 package ideal for space-constrained designs.
  • Fixed Output: No external resistors needed, simplifying design.
