LM1084: For ripple rejection capacitors

Ryu Yamashita

Part Number: LM1084

Hi team,

The data sheet says on page 11 that ripple rejection capacitors other than tantalum or aluminum capacitors should be used.
However, the capacitors in Figure 24 have electrical polarity.
Which type of capacitor should I use for ripple rejection?

Sincerely.
Ryu

Hello Ryu,

You may use either Tantalum/Aluminum or ceramic capacitors as the C_ADJ ripple rejection capacitor. Unlike C_OUT there is no ESR requirement for this capacitor. Please take care to increase C_OUT appropriately if C_ADJ is used. Thanks!

Regards,

Srikanth
