Bryant,

   What's your application and product? do you have some other requirememts? For instance, BOM cost, size, effiency and so on?

Here are some recommendation:

1. LDO: TLV70025 or TLV70525

3. LDO: 5 Vin 1Vout @6A, we do not recommend u to use LDO, because of power consumption 24W. Please use DC/DC : TPS54620 or TPS54618
