Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the operating range of 2.5V to 5.5V.

2. Output Voltage (VOUT):

   • The RT9011 provides a fixed output voltage of 1.8V.

3. Quiescent Current (IQ):

   • When no load is applied (IOUT = 0), the quiescent current is typically 40μA.

4. Dropout Voltage (VDROPOUT):

   • At an output current of 300mA, the dropout voltage is typically 280mV.

5. Load Regulation:

   • For load changes from 0mA to 300mA, the output voltage change is typically 5mV.

6. Line Regulation:

   • For input voltage changes from 2.7V to 5.5V, the output voltage change is typically 5mV.

7. Power Supply Rejection Ratio (PSRR):

   • At 1kHz, the typical PSRR is 60dB.

8. Transient Response:

   • During load steps, the output voltage deviation is typically ±50mV.
