TPS73001 SPICE model

Hi,

I saw that there is no SPICE model available on TI's site for the TPS73001 device.  In fact, it seems like none of the linear regulators have SPICE models available.  Any update as to when these will be available?

    We are in the process of discussing which LDOs will need models and when these can be completed.  For TI products that have models, the models will be available in the products' tool folder.  We are not able to provide a timeline on getting additional models completed.  What parameters are you looking to model?

    Thanks for the response.

    I would like to implement the model into a circuit in TINA for current analysis and noise analysis.

    I'm sorry we will not be able to help you in the near future.  Thank you for your feedback.  This will help us better understand the type of model you need.  An accurate LDO model that accurately models noise is fairly difficult to develop due to parasitics, etc.  I hope you will be able to use the datasheet information and an actual TPS73001 to help you with the information you need.  The TPS73001 does not have an EVM, but because it is a SOT-23 package, it is easy to put on any other EVM.  You could use our generic DEM-SOT23 demonstration fixture.  You can find this in the eStore.  https://estore.ti.com/

    If I can throw my $0.02 in, I would like to see a model for the TPS77350 or a generic LDO model which I could customize.  I am interested in LDO performance and internal shut down / reset during input voltage "brown outs".
