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 RT9193-15GB provides a fixed output voltage of 1.5V. No external components are required to set this voltage.

3. Quiescent Current (IQ):

   • The quiescent current is typically 70μA when the input voltage is 5V and there is no load.

4. Dropout Voltage (VDROPOUT):

   • When delivering a load current of 300mA with an input voltage of 3.3V, the dropout voltage is typically 280mV.

5. Load Regulation (ΔVOUT):

   • The change in output voltage due to load changes from 0mA to 300mA should be less than or equal to 10mV.

6. Line Regulation (ΔVOUT):

   • The change in output voltage due to input voltage variations from 2.5V to 5.5V should be less than or equal to 1mV.

7. Power Supply Rejection Ratio (PSRR):

   • The device offers a typical power supply rejection ratio of 60dB at 1kHz.

8. Transient Recovery Time (tR):

   • For a load step from 0mA to 300mA, the transient recovery time is typically 20μs.

Ensure that all connections are secure and within specified limits to achieve optimal performance. Always refer to the manufacturer's datasheet for more detailed specifications and guidelines.
