你好,我查看LT3045的PDF,没发现官方说不能用MLCC,只发现第19页推荐说用高质量低泄漏电流的陶瓷电容:
Set Pin (Bypass) Capacitance: Noise, PSRR, Transient
Response and Soft-Start
In addition to reducing output noise, using a SET pin bypass
capacitor also improves PSRR and transient performance.
Note that any bypass capacitor leakage deteriorates the
LT3045’s DC regulation. Capacitor leakage of even 100nA
is a 0.1% DC error. Therefore, LTC recommends the use
of a good quality low leakage ceramic capacitor.
