TPS51200: VLDOIN for TPS51200

Chang Fei Yee

Part Number: TPS51200

Hi TI, I am currently using TPS51200 to generate 0.75V VTT and Vref for DDR3 SDRAM.

May I know if VLDOIN can be connected to 3.3V, instead of 1.5V?

Thanks.

Hi Chang Fei,

TPS51200 is a linear regulator.

VLODIN can be connected to 3.3V, but the power loss will be much larger.

I would suggest to connect VLODIN to 1.5V.

Thanks
