Questions and Answers

The AMS1117-3.3 is a fixed 3.3V low dropout linear voltage regulator that can deliver up to 1A output current. It’s widely used to step down higher voltages (like 5V or 12V) to 3.3V, which is required by many modern microcontrollers, sensors, and logic ICs.
-
Input voltage range: Typically up to 12V (absolute max: ~15V)
-
Dropout voltage: About 1.1V @ 800mA
To reliably get 3.3V out, you should input at least ~4.5V.
The 3-pin SOT-223 package pinout is:
-
Pin 1 (ADJ/GND): Ground (for fixed versions like 3.3V)
-
Pin 2 (VOUT): Regulated 3.3V output
-
Pin 3 (VIN): Input voltage
-
Back tab: Connected to VOUT (should be soldered for thermal dissipation)
For stable operation:
-
Input: 10µF electrolytic or ceramic capacitor close to VIN
-
Output: 10µF or higher electrolytic/ceramic capacitor
Low ESR capacitors are recommended for better performance.
