Instructions for Use:

1. Input Voltage (VI): Ensure the input voltage is within the range of 2.7V to 5.5V. The regulator will not function outside this range.
2. Output Voltage (VO): The KIA7818API-U/P provides a fixed output voltage of 1.8V. This is suitable for applications requiring a stable 1.8V supply.
3. Output Current (IO): The device can deliver up to 0.5A continuously. Ensure your load does not exceed this limit to avoid overheating or damage.
4. Quiescent Current (IQ): At an input voltage of 3V and output voltage of 1.8V, the quiescent current is typically 60μA. This value helps in assessing power consumption during operation.
5. Dropout Voltage (VD): For a load current of 300mA, the dropout voltage is approximately 300mV. Keep this in mind when selecting input voltages close to the output voltage.
6. Power Supply Rejection Ratio (PSRR): The PSRR at 1kHz is around 60dB, indicating good noise suppression from the input side.
7. Operating Temperature (TJ): The junction temperature should be maintained between -40°C and 125°C. Ensure adequate heat dissipation if operating near the upper limit.

For optimal performance and longevity, adhere strictly to these parameters and conditions.
