Product Summary

The AMS1117-3.3 is a 1A low dropout voltage regulator. It is designed to provide 1A output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V at maximum output current, decreasing at lower load currents. On-chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry. The AMS1117-3.3 is pin compatible with other three-terminal SCSI regulators and are offered in the low profile surface mount SOT-223 package, in the 8L SOIC package and in the TO-252 (DPAK) plastic package. The applications of the AMS1117-3.3 are High Efficiency Linear Regulators, Post Regulators for Switching Supplies, 5V to 3.3V Linear Regulator, Battery Chargers, Active SCSI Terminators, Power Management for Notebook, Battery Powered Instrumentation.
