TPS7A4501-SP: UVLO/Minimum Input in the Transient Model

Syler Huang
Prodigy 40 points
Part Number: TPS7A4501-SP


Tool/software:

Hi, 

I am using the transient model to run startup simulations. I noticed that there is a UVLO threshold of 1.1V in the model, but it is not mentioned in the documents. Could you please provide more information about this threshold, e.g. min/max values? There is a minimum input voltage value in the datasheet, but its typical value is 1.9V, will the regulator be still operating for Vin between 1.1V and 1.9V?

    Hi Syler,

    This spec will not have min/max thresholds we could provide since it is not included in the datasheet specs that we test. After passing this nominal UVLO, the device will internally be on but correct regulation of the output and guaranteed correct functionality requires the minimum operating VIN voltage to be met. 

    Thanks,

    Sarah
