9 Power Supply Recommendations

The input of the LM809 is designed to handle up to the supply voltage absolute maximum rating of 6.5 V. If the input supply is susceptible to any large transients above the maximum rating, then extra precautions should be taken. An input capacitor is recommended to avoid false reset output triggers due to noise.
