Hi support team,
Confirmation of the title figure.

Is it a typo that has two VOUTs?

What should be between VOUT and GND is a capacitor, not a resistor?

Hello Dice-K,

TPS2116 does have two Vout pins, please check section 10.2 in the datasheet to see more. The resistors to ground are a mistake and should be capacitors. Thanks for bringing this to our attention!

Hi Kalin,
Thank you for your support.

In Section 10.2 and TPS2116EVM, the two VOUTs are bundled together and connected to a single load.
Can each VOUT be connected to two different loads as shown in Figure 3?

Hello Dice-K,

They can be connected to different loads; however, it will be the same supply powering both loads. It would be the same as putting your loads in parallel with a single Vout device. It is not a two channel device. The figure is definitely misleading and I'm working on getting it fixed.

Hi Kalin,
Thank you for your reply.

As shown in the figure below, I have understood that the result is the same whether it branches in the device or on the board.

I hope SLVAEY1 will be corrected so that there is no misunderstanding.
