Instructions for TPS73701DCQR

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 1.7V to 5.5V.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted between 1.8V and 3.3V using external resistors.

3. Dropout Voltage:

   • Keep in mind that the dropout voltage is typically 0.25V at a load current of 500mA. Ensure the input voltage is sufficiently higher than the desired output voltage.

4. Quiescent Current:

   • The device consumes approximately 90μA of quiescent current.

5. Shutdown Mode:

   • When the enable pin (EN) is set to 0V, the shutdown current drops to around 0.1μA.

6. Load and Line Regulation:

   • The load regulation is about 0.1%, ensuring stable output under varying load conditions.
   • The line regulation is approximately 0.05%/V, providing stability with changes in input voltage.

7. Power Supply Rejection Ratio (PSRR):

   • The PSRR is 65dB at 1kHz, which helps in filtering out ripple from the input supply.

8. Operating and Storage Temperatures:

   • The operating junction temperature should not exceed 125°C.
   • The storage temperature range is from -65°C to 150°C.

9. Application Specific Considerations:

   • Always refer to the datasheet for detailed application circuits and design considerations specific to your use case.
