What are the key specifications of the AMS1117-ADJ?

It supports an input voltage up to 18V, provides a 1.25V reference voltage, handles up to 1A output current, and features a typical dropout voltage of 1.2V at 1A.

What should engineers review before using the AMS1117-ADJ?

Engineers should review the thermal resistance specifications, as the SOT-223 package has a junction-to-ambient thermal resistance of 136°C/W, which may limit power dissipation without proper PCB heat sinking.

What is the pinout of AMS1117-ADJ?

Use the AMS1117-ADJ datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about AMS1117-ADJ pinout to locate pins, power rails, and interface signals before layout.
