AMS1117 3.3V, 1A Low Dropout Voltage Regulator IC (SMD SOT-23 Package)

The AMS1117series of adjustable and fixed voltage regulators are designed to produce up to 1A output current and to function at input-to-output differential voltages as low as 1V. The device’s guaranteed maximum dropout voltage is 1.3V, and it drops down at lower load currents.
The reference voltage is modified via on-chip reduction by 1.5%. The current limit is established to reduce the strain on the regulator and power source circuits during overload situations.

Features
