Instructions for Use:

  1. Power Supply Connection:

    • Connect the positive terminal of the power supply to the Vcc pin.
    • Connect the ground terminal of the power supply to the GND pin.
  2. Output Connection:

    • Connect the load to the Vout pin.
    • Ensure the load current does not exceed the maximum output current of 250 mA.
  3. Capacitors:

    • Place a 10 μF electrolytic capacitor between Vcc and GND close to the device to stabilize the input voltage.
    • Place a 1 μF ceramic capacitor between Vout and GND close to the device to stabilize the output voltage.
  4. Thermal Management:

    • Ensure adequate heat dissipation if operating at high temperatures or high load currents.
    • The thermal resistance (θja) is 50 °C/W, so consider a heatsink if necessary.
  5. Operating Conditions:

    • Operate within the specified temperature range (-40°C to 85°C).
    • Store the device within the storage temperature range (-65°C to 150°C).
  6. Regulation:

    • The device provides good load and line regulation, ensuring stable output voltage under varying conditions.
    • The ripple rejection is 70 dB, effectively filtering out input voltage fluctuations.
  7. Dropout Voltage:

    • The dropout voltage is typically 0.3 V, allowing the device to maintain regulation even when the input voltage is close to the output voltage.
  8. Quiescent Current:

    • The quiescent current is typically 1.5 mA, which is relatively low, making the device suitable for battery-powered applications.
