Product Summary
The MIC2954-08YM is a bulletproof efficient voltage regulator with very low dropout voltage (typically 40mV @ light loads and 375mV @ 250mA), and low quiescent current (120µA typical). The quiescent current of the MIC2954-08YM increases only slightly in dropout, thus prolonging battery life. Key MIC2954 features include protection against reversed battery, fold-back current limiting, and automotive load dump protection (60V positive transient). The applicaitons of the MIC2954-08YM are (1)Battery powered equipment; (2)Cellular telephones; (3)Laptop, notebook, and palmtop computers; (4)PCMCIA VCC and VPP regulation/switching; (5)Bar code scanners; (6)Automotive electronics; (7)SMPS post-regulator/dc-to-dc modules; (8)Voltage reference; (9)High-efficiency linear power supplies.
