AMS1117-3.3V with SOT-89 is a Linear Voltage Regulator (LDO) designed by MSKSEMI. It is a low drop-out (LDO) regulator specifically designed to provide 3.3V output with high accuracy and low quiescent current. This voltage regulator is housed in a SOT-89 surface-mount package, and is compliant with RoHS regulations. It features low output noise, fast response time, low dropout voltage, excellent line and load regulation, and over-current and short-circuit protection. The AMS1117-3.3V is an ideal solution for applications such as USB ports, voltage monitoring, and power management systems. It is suitable for both lead-free and traditional reflow soldering processes.
