Input Connection: Connect the input voltage (VIN) to the supply source ensuring it is within the specified range of 4.5V to 28V.
Output Configuration: Adjust the output voltage (VOUT) as needed using the external resistors. Ensure the output voltage is set between 0.8V and 18V.
Current Limiting: The device can provide a continuous output current up to 3A, with a peak of 3.5A. Ensure your application does not exceed these limits to avoid damage.
Thermal Considerations: Monitor the operating temperature. The device is rated for operation from -40°C to 85°C. Use appropriate heatsinking if necessary to maintain this range.
Noise Reduction: To improve power supply rejection, consider adding capacitors at the input and output terminals. This helps in reducing noise and improving stability.
Quiescent Current: Be aware that the quiescent current is around 60μA under no-load conditions, which may be important for low-power applications.
Dropout Voltage: At full load (3A), the dropout voltage is approximately 0.9V. Ensure your input voltage is sufficiently higher than the desired output voltage by at least this amount.
Storage: When storing the device, keep it within the operating temperature range to prevent damage or degradation of performance.
