Product Summary

The LT1175IS8PBF is a negative micropower low dropout regulator. It features 45μA quiescent current, dropping to 10μA in shutdown. A new reference amplifier topology gives precision DC characteristics along with the ability to maintain good loop stability with an extremely wide range of output capacitors. Very low dropout voltage and high efficiency of the LT1175IS8PBF are obtained with a unique power transistor anti-saturation design. Adjustable and fixed 5V versions are available. The applications of the LT1175IS8PBF include: (1)Analog Systems; (2)Modems; (3)Instrumentation; (4)A/D and D/A Converters; (5)Interface Drivers; (6)Battery-Powered Systems.
