LP8866-Q1: LP8866-Q1 Datasheet Recommended Capacitor Questions about VDD & Cpump

Xiaoxiang Liu

Part Number: LP8866-Q1

Hi team,

We found that Recommended Capacitor of VDD& Cpump are different in datasheet between the Table 5-1 and Table 8-7.

If VDD is 5V, should I choose Cvdd = 10 uF & Cpump = 4.7 uF, or Cvdd = 4.7 uF+0.1 uF & Cpump = 10uF?

Thanks,

Xiaoxiang

Hi, xiaoxiang

We suggest using Cvdd = 4.7 uF+0.1 uF & Cpump = 10uF as reference.

table 8-7 is a real case with charge pump disable.
