Part Number:LP5907
Hi team,
Customer change 0402 cap to a same value 0201 cap, and find 1.6MHz 15mV ripple. He added a 0.22uF cap in parallel and this ripple disappear.
Datasheet require output capacitor range is 0.7uF to 10uF, and output capacitor ESR range is 5 to 500mOhm.
1. As impedence and ESR of capacitor is related to frequency, which frequency is specified by datasheet?
2. As specification is same for these two cap below, what's the cause of ripple?
