Product Summary

The MIC2941ABT is a “bulletproof” efficient voltage regulator with very low dropout voltage (typically 40mV at light loads and 350mV at 1A), and low quiescent current (240μA typical). The quiescent current of the MIC2941ABT increases only slightly in dropout, thus prolonging battery life. Key of the MIC2941ABT features include protection against reversed battery, fold-back current limiting, and automotive “load dump” protection (60V positive transient). The applications of the MIC2941ABT include 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.
