Product Summary

The LT1521CS8-3.3TR is a low dropout regulator with micropower quiescent current and shutdown. The LT1521CS8-3.3TR is capable of supplying 300mA of output current with a dropout voltage of 0.5V. Designed for use in battery-powered systems, the low quiescent current, 12μA operating and 6μA in shutdown, makes them an ideal choice. The quiescent current is well controlled; it does not rise in dropout as it does with many other low dropout PNP regulators. The applications of the LT1521CS8-3.3TR include Low Current Regulator, Regulator for Battery-Powered Systems, Post Regulator for Switching Supplies.
