LP8556: Maximum output current

Part Number: LP8556

Tool/software:

Dear team,

My customer is using LP8556 in quite margin state, they need Vout MAX = 21V, VIN 3.3V-4.5V, Iout per channel = 29mA, 6 channel.

Based on the D/S, sometimes it mentioned:

MAX iout is 50mA, but in the table:

May I know if LP8556 is suitable for this application?

If not do we have other suggestions?

Thank you
Charles
