Features & Applications

The MIC2937A-3.3WU is a bulletproof” efficient voltage regulators with very low dropout voltage (typically 40 mV at light loads and 300 mV at 500 mA), and very low quiescent current (160 μA typical)

The quiescent current of the MIC2937A increases only slightly in dropout, thus prolonging battery life. Key MIC2937A features include protection against reversed battery, fold-back current limiting, and automotive “load dump”protection (60 V positive transient).

Features:

  • High output voltage accuracy
  • Guaranteed 750 mA output
  • Low quiescent current
  • Low dropout voltage
  • Extremely tight load and line regulation
  • Very low temperature coefficient
  • Current and thermal limiting
  • Input can withstand:
    • –20 V reverse battery
    • +60 V positive transients
  • Error flag warns of output dropout
  • Logic-controlled electronic shutdown
  • Output programmable from 1.24 V to 26 V(MIC29372)

Applications:

  • Battery Powered Equipment
  • Cellular Telephones
  • Laptop, Notebook, and Palmtop Computers
  • PCMCIA VCC and VPP Regulation/Switching
  • Bar Code Scanners
  • Automotive Electronics
  • SMPS Post-Regulator/ DC to DC Modules
  • High Efficiency Linear Power Supplies
