Instructions for Use
Power Supply Connection:
- Connect the input voltage (VIN) to the power supply within the specified range (4.5V to 5.5V).
- Ensure the power supply is stable and capable of providing the required current.
Output Connection:
- Connect the output (VOUT) to the load requiring 3.3V.
- The maximum continuous output current is 1.2A, with a peak of 1.5A.
Ground Connection:
- Ensure a common ground connection between the input, output, and load to maintain proper operation.
Thermal Management:
- The device has a typical junction-to-ambient thermal resistance of 50°C/W. Use appropriate heatsinking if operating at high temperatures or under high load conditions.
- Ensure the operating temperature does not exceed 85°C.
Load Regulation:
- The load regulation is typically 0.5% to 1.0%, meaning the output voltage will vary slightly with changes in load current.
Line Regulation:
- The line regulation is typically 0.2% to 0.5%, indicating that the output voltage will remain relatively stable even with variations in input voltage.
Ripple Rejection:
- The device provides 60dB to 70dB of ripple rejection, effectively filtering out input voltage noise.
Storage:
- Store the device in a dry environment within the storage temperature range (-65°C to 150°C).
Handling:
- Handle the device with care to avoid mechanical damage or static discharge, which can affect performance.
Testing:
- Before integrating the device into a larger system, test it under various load and input conditions to ensure it meets the required specifications.
