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.
