Hello, all.

Is it possible to connect the output of these chips (TPS7A47, TPS7A33) high aluminum electrolytic capacitor, eg 4700 uF?

Hi Sergey,

That is a large amount of capacitance and ESR may be a concern. These devices were designed and characterized with 10uF ceramic capacitors in mind. Could you help me understand the need for such large aluminum capacitors?

Very Respectfully,
Ryan

Thank you for your response. I want to use in the power supply headphone amplifier instead L78M15 and MC79M15. TPS7A have less noise.
