PRODUCTION DATA.
As listed in the Electrical Characteristics, a minimum of 1.0-µF ceramic capacitance is required to stabilize the BP regulator. To limit regulator noise to less than 10 mV, the value of the bypass capacitor is calculated in Equation 15.
Because Q1 is larger than Q2, and the total gate charge of Q1 is 10 nC, a BP capacitor of 1.0 µF is calculated. A standard value of 1.0 µF is selected to limit noise on the BP regulator.
