(1) The minimum value of capacitance for stability and correct operation is 0.7µF. The Capacitor tolerance should be ± 30% or better over
the temperature range. The full range of operating conditions for the capacitor in the application should be considered during device
selection to ensure this minimum capacitance specification is met. The recommended capacitor type is X7R to meet the full device
temperature spec of -40ºC to 125ºC. See the capacitor section in Application Hints.
