AMS1117 3.3V constant voltage output, up to 1A It is designed to provide up to output current and operate with an input-output difference of up to 1V. The dropout voltage of the device is guaranteed to a maximum of 1.3V, decreasing at lower load currents.
The current limit is set to minimize stress under overload conditions on both the regulator and the power supply circuit.
