LP5996: Output Clarification Required

Varun Gokhale

Part Number: LP5996

Hello,

We want to use LP5996SD-1833/NOPB in one of our designs. However, it is not clear from the datasheet that which output is 1.8V and which output is 3.3V.

Can you please clarify on the same?

Thanks,

Varun

HI Varun,

I found this E2E post that answers your question:

https://e2e.ti.com/support/power-management-group/power-management---internal/f/power-management---internal-forum/451945/lp5996?tisearch=e2e-sitesearch&keymatch=LP5996#

I'm not able to see the NS datasheet archives so I can't verify myself.

Regards,

Nick

Hi Nick,

Thanks for the response. However, when I open the link, it says 'page not found'.

Hi Varun,

Sorry about that, the post I linked is part of our internal forums and is only viewable by TI employees. Here's the text from the responses in that post.

"The first two numbers after the dash (-) stands for VOUT1 and the last two numbers are VOUT2

In the case of the LP5996SD-1833, the output voltages are:
VOUT1= 1.8V (150mA);
VOUT2 = 3.3V (300mA)"

"Correct.

The table with the decoding information was stripped out when NSC datasheets were reformatted to TI standards."

Regards,

Nick
