Instructions for Use:

1. Input Connection: Connect the input voltage to the VIN pin. Ensure the input voltage is within the specified range (7V to 30V).
2. Output Connection: Connect the output voltage to the VOUT pin. The output voltage is fixed at 5.0V.
3. Ground Connection: Ensure a solid ground connection to the GND pin.
4. Capacitors:
   • Input Capacitor: Place a 0.33渭F ceramic capacitor close to the VIN pin to filter out input noise.
   • Output Capacitor: Place a 10渭F electrolytic capacitor close to the VOUT pin to stabilize the output voltage.
5. Thermal Considerations: The device can dissipate heat through its metal tab. Ensure proper heat sinking if operating at high currents or in high ambient temperatures.
6. Load Regulation: The output voltage remains stable over a wide range of load currents, with a typical load regulation of 0.01% per mA.
7. Line Regulation: The output voltage remains stable over a wide range of input voltages, with a typical line regulation of 0.01% per V.
8. Ripple Rejection: The device provides good ripple rejection, typically 70dB, to minimize output voltage fluctuations.
9. Operating and Storage Temperature: The device operates reliably over a temperature range of -40掳C to 125掳C and can be stored between -65掳C and 150掳C.

Additional Notes:

• Overvoltage Protection: The device does not have built-in overvoltage protection. Ensure the input voltage does not exceed the maximum rating.
• Short Circuit Protection: The device includes short circuit protection to prevent damage in case of an output short.
• Reverse Polarity Protection: The device does not have reverse polarity protection. Ensure the input polarity is correct to avoid damage.
