Instructions for Use:
Input Connection:
- Connect the input voltage (VIN) to the positive terminal and ground (GND) to the negative terminal.
- Ensure the input voltage is within the specified range (4.5V to 36V).
Output Connection:
- Connect the output voltage (VOUT) to the load and ground (GND) to the common ground.
- The output voltage is fixed at 5.0V.
Thermal Management:
- Ensure adequate heat dissipation if operating at high output currents or in high ambient temperatures.
- Use a heatsink if necessary to keep the device within the operating temperature range.
Protection Features:
- The device includes thermal shutdown protection, which will activate if the junction temperature exceeds 160°C.
- Ensure the device is not operated in conditions that could cause excessive heating.
Load Regulation:
- The output voltage will remain stable within 0.5% over the load range from 0 to 1.8A.
Line Regulation:
- The output voltage will vary by less than 0.1% per volt change in input voltage.
Ripple and Noise:
- The output ripple and noise should be less than 30mVpp under full load conditions.
Storage and Handling:
- Store the device in a dry environment within the storage temperature range (-55°C to 150°C).
- Handle with care to avoid damage to the leads and package.
Mounting:
- Mount the device on a PCB using standard surface mount technology (SMT) processes.
- Follow the recommended PCB layout guidelines to ensure optimal performance and reliability.
Testing:
- Before final assembly, test the device to ensure it meets the specified parameters and operates correctly under expected conditions.
