Instructions:

1. Supply Voltage (Vcc):

   • Ensure the input voltage is within the range of 1.6V to 5.5V.
   • The typical operating voltage is 3.3V.

2. Output Voltage (Vout):

   • The output voltage is fixed at 3.3V. No external resistors are required for voltage adjustment.

3. Quiescent Current (Iq):

   • The quiescent current is typically 0.5μA, which is very low, making the device suitable for battery-powered applications.

4. Load Regulation:

   • The load regulation is 0.5%, ensuring stable output voltage from 10mA to 500mA load currents.

5. Line Regulation:

   • The line regulation is 0.5%, maintaining a consistent output voltage over the input voltage range of 2.7V to 5.5V.

6. Dropout Voltage (Vdo):

   • The typical dropout voltage is 150mV at a load current of 500mA, allowing the device to operate efficiently even when the input voltage is close to the output voltage.

7. Operating Temperature (Topr):

   • The device operates reliably over a temperature range of -40°C to 85°C.

8. Storage Temperature (Tstg):

   • Store the device in temperatures ranging from -65°C to 150°C.

9. Short-Circuit Protection:

   • The device includes short-circuit protection to prevent damage in case of an output short.

10. Thermal Shutdown:

    • The device features thermal shutdown to protect against overheating, which will automatically turn off the output if the temperature exceeds the safe operating range.
