AMS1117 3.3V Low Dropout Voltage Regulator – SOT-223

The AMS1117 has a series of adjustable and fixed voltage regulators. This is a 3.3V Output Version of AMS1117. It provides up to 1A output current. It can also operate on 1V input to output differential. The dropout voltage of the device is maximum 1.3V, which decreases at lower load currents.

On-chip trimming adjusts the reference voltage to 1.5%. The current limit of AMS1117 3.3V is preset to minimize the stress under overload conditions on both the regulator and power source circuit.
