ADP5073 can't provide current according to specification

Category: Choose a category
Product Number: ADP5073


In the selection table for inverting regulator it's specified that ADP5073 can deliver 1.375A.

Here is simulation setup where I check its capability to generate -30V from +5V.

The values of Rfb, Rft, L1, etc. I took from datasheet hint table.

I tried with two loads - 1k and 100Ohm

1k - Ok, whereas 100 Ohm failed.

Any comments ?
