FAQ
Q: Can AMS1117-3.3 power an ESP32 with WiFi active?
A: The ESP32 can draw up to 500mA peak during WiFi transmission. The AMS1117 is rated at 800mA, so it can handle this — but ensure adequate input voltage (min 4.6V for 3.3V output) and add a 100μF capacitor on the output for stability.
Q: What is the minimum input voltage for AMS1117-5V?
A: Minimum input = 5V + 1.3V dropout = 6.3V. Use a 7.5V–12V source for reliable 5V output.
Q: Can I use AMS1117-ADJ for adjustable output?
A: This listing is for fixed-output modules. For adjustable output, use the AMS1117-ADJ IC with external resistors (Vout = 1.25V × (1 + R2/R1)).
