Instructions for Use:

  1. Supply Voltage:

    • Ensure the supply voltage is within the range of 4.5V to 5.5V to avoid damage to the device.
  2. Output Current:

    • The device can provide up to 300mA of output current, with typical performance at 200mA.
  3. Quiescent Current:

    • The quiescent current is typically 0.5mA but can range from 0.1mA to 1.0mA.
  4. Shutdown Current:

    • When the device is in shutdown mode, the current consumption is very low, typically 0.5μA.
  5. Output Voltage Range:

    • The output voltage can be set from 0V to Vcc - 1.2V.
  6. PSRR (Power Supply Rejection Ratio):

    • The device has good power supply rejection, with a typical value of 70dB over the frequency range of 10 Hz to 100 kHz.
  7. Line Regulation:

    • The line regulation is typically 0.01% per volt, ensuring stable output voltage even with variations in input voltage.
  8. Load Regulation:

    • The load regulation is typically 0.02% per milliamp, maintaining a consistent output voltage under varying load conditions.
  9. Thermal Shutdown:

    • The device will automatically shut down if the junction temperature exceeds 150°C to prevent damage.
  10. Operating Temperature:

    • The device is designed to operate within the temperature range of -40°C to 85°C.
  11. Storage Temperature:

    • Store the device in an environment where the temperature ranges from -55°C to 150°C.
  12. Handling Precautions:

    • Handle the device with care to avoid static discharge, which can damage the internal components.
    • Follow proper soldering techniques to ensure reliable connections and prevent thermal damage during assembly.
