Product Summary

The mic5205bm5 is an efficient linear voltage regulator with ultralow- noise output, very low dropout voltage (typically 17mV at light loads and 165mV at 150mA), and very low ground current (600μA at 100mA output). The mic5205bm5 offers better than 1% initial accuracy. Applications are (1)Cellular telephones; (2)Laptop, notebook, and palmtop computers; (3)Battery-powered equipment; (4)PCMCIA VCC and VPP regulation/switching; (5)Consumer/personal electronics; (6)SMPS post-regulator/dc-to-dc modules; (7)High-efficiency linear power supplies.
