AMS1117 Voltage Regulator

Description

The AMS1117 series of adjustable and fixed voltage regulators are designed to provide up to1A output  current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V, decreasing at lower load currents.
On-chip trimming adjusts the reference voltage to 1.5%. Current limit is set to minimize the stress under overload conditions on both the regulator and power source circuitry.
