Instructions for Use:

1. Supply Voltage (Vcc):

   • Ensure the supply voltage is within the range of 4.5V to 30V.
   • Avoid exceeding the maximum supply voltage to prevent damage.

2. Output Current (Iout):

   • The device can provide a continuous output current of up to 2.0A, with a typical value of 1.5A.
   • For higher currents, ensure adequate heat dissipation.

3. Thermal Shutdown (Tsd):

   • The device will automatically shut down if the junction temperature exceeds 160°C to prevent thermal damage.
   • Allow the device to cool before resuming operation.

4. Storage Temperature (Tstg):

   • Store the device in an environment where the temperature ranges from -40°C to 125°C.

5. Junction-to-Case Thermal Resistance (Rθjc):

   • The thermal resistance between the junction and the case is 15°C/W.
   • Use a heatsink or other cooling methods if operating at high currents or in high ambient temperatures.

6. Dropout Voltage (Vdo):

   • The dropout voltage is typically 0.8V when the output current is 1.5A and the supply voltage is 5V.
   • Ensure the input voltage is at least 0.8V higher than the desired output voltage.

7. Quiescent Current (Iq):

   • The quiescent current is typically 2.5mA and can go up to 5mA at 5V supply voltage with no load.
   • This current is necessary for the internal regulation circuitry.

8. Line Regulation (ΔVout/ΔVin):

   • The line regulation is typically 0.01%/V, indicating a stable output voltage even with changes in input voltage.

9. Load Regulation (ΔVout/ΔIout):

   • The load regulation is typically 0.1%/A, ensuring a stable output voltage even with changes in load current.

10. Ripple Rejection (PSRR):

    • The power supply rejection ratio (PSRR) is typically 70dB at 100Hz, effectively reducing input ripple on the output.

Additional Notes:

• Always use appropriate decoupling capacitors on the input and output to ensure stability and reduce noise.
• For optimal performance, refer to the datasheet for detailed application circuits and layout guidelines.
