AMS1117 5V Voltage Regulator IC | 800mA LDO Regulator – SOT-223

The AMS1117 5V is a reliable low-dropout (LDO) linear voltage regulator designed to provide a stable 5V outputwith up to 800mA of load current. Housed in a compact SOT-223 package, it is ideal for space-constrained embedded systems, power modules, IoT devices, and development boards.

With a dropout voltage as low as 1V, the AMS1117 delivers consistent output regulation even when input voltage is only slightly above the desired 5V level. It features low standby current (2mA) and excellent line/load regulation, making it highly efficient and suitable for battery-based and low-noise power applications.

The regulator includes thermal shutdown and current limit protection, ensuring safe and stable operation under varying load conditions. Its precision trimming guarantees ±2% output voltage accuracy, contributing to reliable and predictable circuit performance.
