AMS1117-3.3V
Product Introduction
AM11117 is a very classic linear voltage regulator module that, after decades of development, can be made very small in size, only 6.5x7x1.5mm, and even integrates overcurrent and high temperature protection internally. In addition, due to the use of physical methods to stabilize the voltage, the voltage it provides is also very clean, with almost no noise, so you can see its presence almost anywhere there is an MCU

Pin Definition
Our AM11117 module simplifies the difficulty of use, with only three pins overall, namely:
VIN: Power input terminal, input voltage greater than 1.2V output voltage
GND: The grounding terminal of the module, which is also the reference point for zero voltage
OUT: Power output terminal, outputting a specified voltage, such as 3.3V
Output ripple measurement
We used sine waves to simulate the scenario of input voltage fluctuations, and it can be seen that even if the input voltage fluctuates above 1V, the voltage fluctuation is only 60mV
The voltage rise curve waveform when starting the power supply is almost close to the waveform at the input end, and it can immediately maintain a stable output waveform when reaching the required stable voltage
