Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
outside of its stated operating conditions.
Note 2: Human body model, 1.5 k
Ω in series with 100 pF.
Note 3: Power dissipation
≤ 0.75W.
Note 4: Recommended minimum load capacitance of 0.01 µF to limit high frequency noise.
Note 5: Typical thermal resistance values for the packages are:
