Hey Lucia,
Unfortunately, we are stuck with the blank version because the -1 version has too narrow an LDO input voltage. The -2 version has no automatic sequencing.
The idea we are looking at is using 2x TPS65262 in parallel. So LDO1 in parallel with…
Hi Hale,
We have written 2 white papers and 1 software tool on paralleling LDO's using ballast resistors. We are in the process of adding more LDO's to the software tool, and we wish to update this year for the TPS7A52/3/4. You can easily parallel…
Part Number: TPS7A74 Other Parts Discussed in Thread: TPS7A57 , TPS7A54 , TPS7A53 Dear Sirs,
May I use 2 LDOs in parallel to get a double output current?
My customer wants to use 2pcs TPS7A7401 to do such design.
Please help to advise.
Thanks.
Part Number: LP8733 Other Parts Discussed in Thread: AM2434 , Considering using the DP87334 device, which is pre-configured for the Sitara AM2434 SoC. I do not want to have to program/configure it to modify the default settings if possible.
The DP8733x…
Hello,
Yes, you can parallel the TPS7A4700. We have released new resources last year detailing how to do this and an example for this LDO is listed in the first link below. You will want to use the digital voltage control pins, also known as the ANYOUT…
Hi Chen,
Yes, you can parallel the TPS7A39 using the ballast resistor technique. We have white papers and a software tool which we released on this technique last year (copied below), however we will need to add the TPS7A39 to the calculator before you…
Thanks Wade, promising results. I need to do an analysis of the pdn network between our loads and the bulk dcaps at ldo outputs to assess if the 500ns rise/fall time is reasonable approximation of our application. I'll follow up when i get that answer…
Part Number: TPS7H1101A-SP Is it possible to connect 3 LDOs in parallel - similar to the dual configuration shown in Figure 20 of the datasheet?
If so, what would the connections / external component considerations be?
Hi Vijay,
The TPS7A8300RGRR is one of the better LDOs on the market but there are better devices to use here. I would consider the TPS7A94 which is the lowest noise LDO on the market (it has 46% lower noise than the next best LDO on the market). It also…
Hi Antonio,
I just wanted to let you know that a new revision of the calculator has now been released. It includes your TPS7A85 LDO along with 7 others that have been added. You can find the calculator here:
