Hi ,
How much current do you need in your application? TPS7A33 is a similar LDO rated for 1A.
If you would prefer to parallel two TPS7A30 to current share, the following TI Design would be a good reference for you:

Hi Niels,
We do not have a 4A negative LDO at this time; however, the principles in the following reference design should be able to be applied to a negative LDO such as TPS7A33 http://www.ti.com/tool/TIDA-00270?keyMatch=current%20sharing&tisearch=Search…
Alex,
Per TIDA-00270, you'll have to sense current at the inputs of each LDO with the OPA333. Like you said, you can set the master output voltage with ANYOUT pins and leave the ANYOUT pins floating for the slave device. The OPA333 output should be connected…
Other Parts Discussed in Thread: ISO3088 , TPS7A49 , TPS7A47 , TIDA-00270 Hi,
I have to manage a linear regulator to convert 12Vdc to 5Vdc with a maximum current of 150mA. I had a look to the file ISO3088, and the TPS7A49 option It could be a good option…
Hi Jerry,
Unfortunately we do not have any negative LDOs that are able to handle 2 A; however, we do have several negative voltage regulators that could be used in a current sharing application. You can find our selection of negative voltage regulators…
Hi Tiffany,
We do not have a single chip solution for 6 A with your required voltage rails; however, we do have a couple of TI Designs that discuss methods for using a couple LDOs to meet the current requirement through current sharing:
Very Respectfully…
Hi Alice,
How much current do you need? Please note the principles contained in the following TI Designs can be applied to multiple LDOs.
Very Respectfully,
Ryan
Hi Ryan,
Thanks for your suggestion. I may need to use adjustable output mode option as well in addition to ANY-OUT, so how should I connect FB pin during 2x LDO in parallel.
I understand ANYOUT from your reference schematic (TIDA-01232) that ANYOUT config…
Hi Ikon,
While it is possible to parallel two LDOs, is there a reason you do not want to use an LDO with a higher current rating such as TPS7A83A, TPS7A84A or TPS7A85A?
Here are a couple of TI-Designs that go into methods of paralleling LDOs. You should…
