TPS7A7200: Input Impedance

Part Number: TPS7A7200

Hi E2E,

Good day!

A customer of mine is doing some test on their TPS7A7200RGWR and would like to know the internal input impedance to GND of this part. Do we have this information?

Best regards,

Franz

    Hi Franz,

    The datasheet specifies the ground current in figures 13, 14 and 15 in the datasheet.
    You can take the input voltage and divide by this ground current to estimate the input impedance.
    If the customer is requesting this for the shutdown mode, they should use figure 15.

    Thanks,
