TPS7B4250-Q1 dropout voltage

Other Parts Discussed in Thread: TPS7B4250-Q1

I would like to confirm the dropout voltage of TPS7B4250-Q1.
I have got the question of it from the customer.

The conditions are;
1. Vin = 5.8V, Io = 40mA
2. Vin = 5.8V, Io = 30mA

Could you please estimate the maximum value?

Best regards,
Atsushi Yamauchi

    Hi Atsushi-san,

    It can be seen fromt the datasheet tha under 10mA load, 265mV is the max dropout, under 50mA, 1000mV is maximum, I would say, for 40mA, the max value is around 800mV.

    Our designer is doing simulatin on this now, should be able to provide the exact result before next week.

    Best regards

    Hi Atsushi-san,

     

    Please see the simulation result for TPS7B4250-Q1 dropout voltage per below:

     

    Dropout_max_30mA=575mV;

    Dropout_max_40mA=777mV.

    Just a reminder above result is not tested during production program, so this is guaranteed by design.

    Best regards
