What are the primary applications for this regulator?

It is commonly used in computer motherboards, graphic cards, LCD monitors, DVD players, and as a post-regulator for switching power supplies.

What should engineers review before using this component?

Engineers should review the thermal resistance of the chosen package (SOT-223, TO-252, or SOT-89) and ensure the PCB copper area is sufficient to manage power dissipation.

What are the key specifications of the AMS1117-1.8V?

It delivers 1A output current, has a 1.3V dropout voltage at 1A, 2mA standby current, and 2% output voltage accuracy.

What are the sourcing risks for the AMS1117-1.8V?

The component is widely available, but users should verify stock levels and lead times with distributors for high-volume production.

What is the pinout of AMS1117-1.8V?

Use the AMS1117-1.8V datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about AMS1117-1.8V pinout to locate pins, power rails, and interface signals before layout.
