TPS7A4501-SP: Line Regulation

Part Number: TPS7A4501-SP

Do we have a table or graph showing typical input line regulation?

I see the specification at Vin from 2.9V to 20V, OUT changes 2.5mV typ and 6.5mV max.

A graph would show if the voltage is increasing or decreasing with input line voltage

  • Hi Steve,

    We'll look into this and get back to you on Monday.

    Thanks,

  • Hi Steve,

    Line regulation can show a positive or negative change. Often the VOUT change will be in the same direction as the VIN change, but that is not always the case due to factors like temperature. I would generally recommend treating the parameter as a +/- value if you want to cover corner conditions.

    The TID radiation report for this device appears to show VOUT changing in the same direction as VIN. VIN is swept from 2.9V to 20V with a 1mA load, and the resulting change in VOUT had an average value of 0.107mV (pre-radiation). This test is performed at 25C, while the datasheet spec accounts for the full temperature range, radiation, and aging. 

    Thanks,
