Instructions for Use:

  1. Input Voltage (VIN):

    • Ensure the input voltage is within the range of 7.0 V to 12.0 V to avoid damage to the regulator.
  2. Output Voltage (VOUT):

    • The output voltage is regulated to 5.0 V ± 0.2 V. Ensure the load current is within the specified range to maintain this regulation.
  3. Output Current (IOUT):

    • The maximum continuous output current is 100 mA. Exceeding this may cause the regulator to overheat or shut down.
  4. Line Regulation:

    • The line regulation is 0.01% over the input voltage range, ensuring stable output voltage even with input variations.
  5. Load Regulation:

    • The load regulation is 1.0% over the load current range, maintaining output stability under varying load conditions.
  6. Dropout Voltage:

    • The dropout voltage is 1.5 V at full load. Ensure the input voltage is at least 1.5 V higher than the output voltage to maintain regulation.
  7. Quiescent Current:

    • The quiescent current is 5 mA at no load, which is important for low-power applications.
  8. Thermal Shutdown:

    • The regulator will shut down if the junction temperature exceeds 160°C to prevent damage.
  9. Short-Circuit Protection:

    • The regulator has a short-circuit current limit of 350 mA to protect against output shorts.
  10. Capacitor Requirements:

    • A 0.33 μF capacitor should be placed close to the input pin to stabilize the regulator.
    • A 0.1 μF capacitor should be placed close to the output pin to ensure stability and reduce output ripple.
  11. PCB Layout:

    • Ensure proper heat dissipation by using a large copper area around the regulator if high output currents are expected.
    • Keep the input and output capacitors as close as possible to the regulator pins to minimize parasitic inductance and improve performance.
