Other Parts Discussed in Thread: LP38513-ADJ

Hi,all

I am planning to use LP38513-ADJ for conversions from 2.5V rail to 1.9V.The current needed is 2A. In the datasheet the maximum output current is 3A,but when i evaluate this LDO by WEBENCH,the maximum output current is only 1.4A,Is this right?

I am looking forward your reply.

Thanks.

Hi,

Thanks for alerting us to this problem. The LP38513-ADJ dropout voltage was set a little too conservatively in the WEBENCH Power Designer, limiting the load current for your design. It's adjusted now. Please try your design again.

Hi,I am grateful for your help.

Now I can save one LDO with using LP38513-ADJ for 2A needed.

Thanks.
