Instructions for Using the AMS1117-2.5
Input Voltage (VIN):
- Ensure the input voltage is within the range of 2.3V to 15V.
- The input voltage should be at least 1.3V higher than the output voltage to maintain regulation.
Output Voltage (VOUT):
- The AMS1117-2.5 provides a fixed output voltage of 2.5V.
- No external resistors are required to set the output voltage.
Output Current (IOUT):
- The device can provide a continuous output current of up to 800mA.
- For higher current requirements, consider using a heatsink or a more powerful regulator.
Thermal Considerations:
- The device has a thermal shutdown feature that activates at approximately 160°C to protect against overheating.
- Ensure adequate heat dissipation, especially when operating at high currents or in high ambient temperatures.
Storage Temperature (TSTG):
- Store the device in an environment with temperatures ranging from -40°C to 125°C.
Circuit Design:
- Use appropriate input and output capacitors to ensure stability and reduce ripple.
- A typical configuration includes a 10μF electrolytic capacitor on the input and a 10μF electrolytic capacitor on the output.
PCB Layout:
- Place the AMS1117-2.5 as close as possible to the load to minimize trace resistance and inductance.
- Use wide traces for power and ground connections to reduce resistance and improve heat dissipation.
Testing:
- Before finalizing the design, test the circuit under various conditions to ensure it meets the required specifications.
- Monitor the temperature of the regulator during operation to ensure it does not exceed the maximum operating temperature.
