Instructions for AOZ5019QI

1. Power Supply Connection:

   • Connect the input voltage (VIN) between the IN pin and GND.
   • Ensure the input voltage is within the range of 2.7V to 5.5V.

2. Output Configuration:

   • The output voltage (VOUT) is fixed at 1.8V. No external components are required for setting this voltage.

3. Quiescent Current Management:

   • The quiescent current is typically 60μA at an input voltage of 5V. This low current helps in minimizing power consumption.

4. Load Regulation:

   • The device maintains load regulation within 1.5% as the load current changes from 1mA to 200mA.

5. Dropout Voltage Consideration:

   • Keep the dropout voltage in mind, which is typically 300mV at a load current of 200mA. This ensures stable operation even at low input voltages.

6. Shutdown Operation:

   • To shut down the device, pull the SHDN pin to GND. In shutdown mode, the supply current reduces to approximately 1μA.

7. Power Supply Rejection Ratio:

   • The device provides a PSRR of 60dB at 1kHz, effectively rejecting variations in the input voltage.

8. PCB Layout Recommendations:

   • Place the input and output capacitors close to the respective pins to ensure stability and performance.
   • Use a ground plane to reduce noise and improve thermal performance.

9. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at higher currents or in environments with elevated temperatures.
