TPS65023-Q1: LDO PSRR

Alberto Fuggetta1

Part Number: TPS65023-Q1
Other Parts Discussed in Thread: TPS65023, LM26480

Hi,

I was not able to find any PSRR data for the internal LDOs of the TPS65023.

Do you by chance have any data?

Thanks

Regards,

Alberto

    Hi,

    I have forwarded your request to my colleague who supports this device. Due to US holidays he is out of office today and he will provide you the feedback once he comes back to office on 30th Nov-20.

    Regards,

    Alberto,

    If there is no PSRR spec in the datasheet, then this data was not collected for the TPS65023 device.

    I am not sure what type of application this is or what SoC you are powering with the PMIC, but you can take a look at the LM26480, which is a similar PMIC (2 Bucks, 2 LDOs) that has a PSRR spec in the datasheet: PSRR (Power supply ripple rejection) F = 10 kHz, load current = IMAX, Typical = 45 dB
