Part Number: TPS7A11
Other Parts Discussed in Thread: LP5910, , TPS7A10

Hi team,

cusotmer would like to compare the PSRR curves of LP5910 and TPS7A11.
Could you provide the PSRR curves that based on the following conditions?
Vin: 2.0V
Vout: 1.8V
Iout: 300mA
Range: 1kHz ~ 1MHz

BR,

    Hi SHH,

    Having only 200 mV of dropout between Vin and Vout will have a significant adverse effect on the PSRR value, please see PSRR data for TPS7A10 device (same family of TPS7A11 device) with 300 mA of IOUT and 200mV of dropout.

    What is the targeted PSRR value the customer is looking for in that frequency range?

    BR,

    Haidar

    Hi SHH,
    Since it has been a week without a reply, I assume that my post answered your question, so I am going to close this thread. If this is not correct, please feel free to post again.
