AMS1117-3.3 voltage regulator

The AMS1117 series of flexible, adjustable, and fixed power supply regulators are easy to use and are guaranteed against short circuits. It includes thermal protection circuitry which shuts down the circuit if the temperature get exceeds. The module has a pin-compatible three-terminal integrated circuit. Hence, it is great for devices having lower dropout voltage, precise tolerance, and improved stability with temperature.

The AMS1117-3.3 are low dropout three-terminal regulators with 1A output current capability. These devices have been optimized for low voltage where transient response and minimum input voltage are critical. On-chip thermal limiting provides protection against any combination of overload and ambient temperatures that would create excessive junction temperatures. Unlike PNP-type regulators where up to 10% of the output current is wasted as quiescent current, the quiescent current of the AMS1117 flows into the load, increasing efficiency.
