Product Summary

The LT1117IST-3.3 is a positive low dropout regulator. The LT1117IST-3.3 can be used in (1)Active SCSI Terminators; (2)High Efficiency Linear Regulators; (3)Post Regulators for Switching Supplies; (4)Battery Chargers; (5)5V to 3.3V Linear Regulators. The low profile surface mount SOT-223 package allows the device to be used in applications where space is limited. Dropout voltage is guaranteed at a maximum of 1.2V at 800mA, decreasing at lower load currents. Current limit is also trimmed in order to minimize the stress on both the regulator and the power source circuitry under overload conditions.
