The AMS1117-1.8 is a three-pin, surface-mount, low-dropout (LDO) linear voltage regulator with a SOT-223-3L package from Taiwan General Microcircuits (TWGMC). It is ROHS compliant, meaning it meets the European environmental standards for hazardous substances. The AMS1117-1.8 is capable of providing a regulated output of 1.8V with a maximum input voltage of 7V and a maximum output current of 800mA. Additionally, it has an operating junction temperature range from -40C to +125C. This makes it suitable for use in a wide range of temperature environments. As a Linear Voltage Regulator, it is designed to step down a higher input voltage to a lower output voltage while providing a smooth and consistent voltage.
