AMS1117-3.3-LDO 3.3V 1A Fixed Output Linear Voltage Regulator

Description

GENERAL DESCRIPTION

The AMS1117 series of adjustable and fixed voltage regulators is designed to provide up to 1A output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed to be at least 1.3 volts, decreasing at lower load currents. On-chip trimming adjusts the reference voltage to 1.5%. The current limit is set to minimize the stress under overload conditions on both the regulator and power source circuitry. The AMS1117 devices are 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.
