Silan 士兰微 SA1117 1A LDO VOLTAGE REGULATOR

The SA1117 is a positive low voltage dropout regulator, voltage dropout is only 1.2V at 1A. 

SA1117 has two versions: the fixed version and the adjustable version. VOUT has a tolerance of less than 1% for fixed versions 1.5V, 1.8V, 2.5V, 3.3V, 5.0V and adjustable version or 2% output accuracy for fixed version 1.2V.

The SA1117 integrates overheating protection and current limit circuits. It is an suitable for all electronic products.
