Other Parts Discussed in Thread: TPS51200, TPS51206

Hola,

Can anyone help transfer these questions to someone who can answer it？ Thank you again...

1. Both TPS51206 & TPS51200 are linear regulators so they are belongs LDO？right？

2. What's the different between TPS5120X and general regulator？

3. What's the benefit of source/sink current？

    There seems to be some cross posting of these devices between non-isolated dc-dc and linear regulators forums.  I will move it to linear regulators, but I can answer these general questions,

    1.  Yes both TPS51200 and TPS51206 are linear regulators.

    2.  If you mean switching buck converter when you say "general regulator" then:

    Linear regulator is generally simpler than dc-dc converter.  Less external components are required (no inductor, no external compensation or BST capacitor).  Lnear regulator is less efficient in most cases.  Linear regulator is generally quieter as there is no switching noise.

    3.  For operation with DDR memory, source and sink of current is required for VTT.  Both TPS51200 and TPS51206 are intended for DDR applications.
