TPS767D325: LDO 1 expected output is not getting

LAXMI KANT TIWARI

Part Number: TPS767D325

Hello,

I have designed a dual power source for my circuit using TPS767D325 as follows

I have printed PCB and after soldering these components. I am getting LDO2 output 3.3V as usual and LDO1 output voltage level is supposed to get 2.5V but I am only getting 0.8V. What could be wrong here?

Update1: I have bought TPS767DT301 by mistake instead of TPS767DT325. How can I use it to get desired power supply.

Okay I got the answer. I have connected 110K and 100K in feedback from out1 to FB.
