Working Principle of AMS1117 3.3V Module

The AMS1117 regulator works by maintaining a constant output voltage regardless of minor changes in input voltage or load conditions.

When DC voltage is applied to the input:

The regulator IC adjusts internal resistance
Excess voltage is dissipated as heat
Output remains constant at 3.3V
Capacitors stabilize voltage ripple

This ensures that sensitive electronics receive a clean and stable power supply.
