AMS1117 Datasheet | EVVO

DESCRIPTION The AMS1117 is a positive low voltage dropout regulator; typical voltage dropout is only 1.2V at 1A. AMS1117 provides two versions: fixed and adjustable versions. VOUT has a tolerance of less than 1.5% for fixed versions 1.2V 1.5V, 1.8V, 2.5V, 3.3V, 5.0V and adjustable version or 2% output accuracy for fixed version 1.2V. The AMS1117 offers some key features include thermal shutdown and current limiting. It is suitable for all electronic products.
