Instructions for Use:

  1. Supply Voltage (Vcc):

    • Ensure the supply voltage is within the range of 2.0V to 5.5V.
    • Exceeding this range can damage the device.
  2. Output Current (Iout):

    • The device can provide up to 100mA of output current.
    • Do not exceed this limit to avoid overheating or damage.
  3. Quiescent Current (IQ):

    • The quiescent current is very low at 1.0μA, making it suitable for low-power applications.
  4. Dropout Voltage (Vdo):

    • The dropout voltage is 0.3V, which means the input voltage should be at least 0.3V higher than the output voltage for proper regulation.
  5. Operating Temperature:

    • The device operates reliably between -40°C and 125°C.
    • Avoid operating outside this range to prevent performance degradation or failure.
  6. Storage Temperature (Tstg):

    • Store the device between -65°C and 150°C to ensure long-term reliability.
  7. Load Regulation:

    • The load regulation is 2.0mV per 100mA change in load current, indicating good stability under varying loads.
  8. Line Regulation:

    • The line regulation is 0.01% per volt change in input voltage, ensuring stable output even with fluctuations in input voltage.
  9. Ripple Rejection:

    • The ripple rejection is 70dB, effectively filtering out noise from the input power supply.

Additional Notes:

  • Always use appropriate decoupling capacitors on both the input and output to ensure stable operation.
  • For optimal performance, place the device close to the load and use short, wide traces for power connections.
  • Refer to the datasheet for detailed application circuits and further guidelines.
