* S- J3 _- F: E3 oSVR
Half Supply Voltage Decoupling (Ripple Rejection)
% d  c  |8 u, o/ z5 rThe Supply Voltage Ripple Rejection (SVRR) is measured with an electrolytic capacitor of 150 µF on pin SVR using a bandwidth of 20 Hz to 22 kHz. A larger capacitor value on pin SVR improves the ripplerejection behavior at the lower frequencies.

根據 50% 電容降額（Derating）原則，大於或等於 VCC 電壓即可。
