Input Voltage (VIN):
- Ensure the input voltage is within the operating range of 4.5V to 28V. Exceeding this range can damage the device.
Output Voltage (VOUT):
- The output voltage can be adjusted between 0.8V and 18V. Use external resistors to set the desired output voltage according to the datasheet formula.
Quiescent Current:
- Keep in mind that the quiescent current is approximately 70μA when no load is present and VOUT is set to 5V.
Dropout Voltage:
- The dropout voltage is typically 0.3V at an output current of 1A and an input voltage of 5V. Ensure the input voltage is sufficiently higher than the output voltage to maintain regulation.
Load Regulation:
- The load regulation is around 0.1% as the output current changes from 0 to 1A. This indicates good stability under varying loads.
Line Regulation:
- Line regulation is about 0.01% as the input voltage varies from 4.5V to 28V, ensuring stable output despite input fluctuations.
Ripple Rejection:
- The device provides a ripple rejection of 60dB at 120Hz, which helps in filtering out noise from the input supply.
Thermal Shutdown:
- The device has thermal protection that activates at approximately 160°C to prevent damage due to overheating.
