Features & Applications

The MIC2940A-5.0WU TR is a "bulletproof" efficient voltage regulator with very low dropout voltage (typically 40 mV at light loads and 350 mV at 1 A), and low quiescent current (240 µA typical). The quiescent current of the MIC2940A increases only slightly in dropout, thus prolonging battery life.

Key MIC2940A features include protection against reversed battery, fold-back current limiting, and automotive "load dump" protection (60 V positive transient). The MIC2940 is available in both fixed voltage (3.3 V, 5 V, and 12 V) and adjustable voltage configurations. The MIC2940A-xx devices are three pin fixed voltage regulators. A logic-compatible shutdown input is provided on the adjustable MIC2941A, which enables the regulator to be switched on and off.

Key Features :

  • High output voltage accuracy
  • Guaranteed 1.25 A 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 and +60 V positive transients
  • Logic-controlled electronic shutdown
  • Output programmable from 1.24 V to 26 V(MIC2941A)
  • Available in TO-220, TO-263, TO-220-5, and TO-263-5 packages.

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
  • Voltage Reference
  • High Efficiency Linear Power Supplies
