Instructions for Using AMS1117S OT223 AMS1117-3.3:
Input Voltage:
- Ensure the input voltage is within the range of 3.0V to 15.0V.
- Higher input voltages can cause overheating and damage the regulator.
Output Voltage:
- The output voltage is fixed at 3.3V.
- Use appropriate capacitors on the input and output to stabilize the voltage and reduce ripple.
Output Current:
- The maximum continuous output current is 1.0A.
- For higher currents, consider using a heatsink or a more powerful regulator.
Dropout Voltage:
- The dropout voltage is approximately 1.3V at full load.
- Ensure the input voltage is at least 1.3V higher than the output voltage to maintain regulation.
Quiescent Current:
- The quiescent current is typically 5.0mA.
- This is the current consumed by the regulator when it is active but not supplying any load.
Shutdown Current:
- The shutdown current is very low, around 0.001A.
- Use the enable pin to turn the regulator on and off as needed.
Operating Temperature:
- The operating temperature range is from -40°C to 125°C.
- Ensure adequate cooling if operating in high-temperature environments.
Storage Temperature:
- The storage temperature range is from -65°C to 150°C.
- Store the regulator in a dry and cool place to prevent damage.
Capacitor Recommendations:
- Use a 10μF tantalum or ceramic capacitor on the input side.
- Use a 10μF tantalum or ceramic capacitor on the output side to ensure stability.
PCB Layout:
- Place the input and output capacitors as close as possible to the regulator.
- Ensure good thermal management with a heatsink if necessary.
Enable Pin:
- If the enable pin is used, connect it to a logic high level to activate the regulator.
- Connect it to ground to shut down the regulator.
Safety Precautions:
- Always use appropriate fuses and protection circuits to prevent damage from overvoltage or short circuits.
- Handle the regulator with care to avoid static discharge which can damage the component.
