Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 2.7V to 5.5V. Exceeding this range can damage the device.

2. Output Voltage (VOUT):

   • The output voltage is adjustable from 0.8V to 3.6V. Set the desired output voltage using external resistors according to the datasheet formula.

3. Quiescent Current:

   • The quiescent current is typically 25渭A at an input voltage of 5V. This low current consumption makes it suitable for battery-powered applications.

4. Load Regulation:

   • The load regulation is specified as 0.2% from 1mA to 150mA, indicating minimal change in output voltage with varying loads.

5. Line Regulation:

   • Line regulation is specified as 0.1% over the input voltage range from 2.7V to 5.5V, ensuring stable output voltage despite changes in input voltage.

6. Dropout Voltage:

   • At a load current of 150mA, the dropout voltage is typically 300mV. Keep this in mind when selecting the input voltage to ensure efficient operation.

7. Power Supply Rejection Ratio (PSRR):

   • The PSRR is typically 70dB at 1kHz, providing good noise suppression and stability against input voltage variations.

8. Layout Considerations:

   • Place the RT8482GS close to the power supply input capacitor to minimize noise.
   • Use short leads and wide traces for ground connections to reduce parasitic inductance and resistance.

9. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at high currents or in high ambient temperatures.

10. Capacitor Selection:

    • Choose input and output capacitors with appropriate values as recommended in the datasheet to ensure stability and performance.
