Hi Team,

i have 2 questions,

[1] Tell me the Frequency property of PSRR at LDO Regulators ?

If possible, show the plots at below conditions.

Vin - Vout : 0.5V , 1.5V

Iout = 40mA

[2] Buck Regulators,does the parameter [Vout_Bx_DC] include ripple voltage in datesheets ?

Thanks.

Hi Kaz,

2. It does not, and right below this is the ripple information which you may want to take into account.

Thanks,
Field

Hi Field,

Thank you for your answer.

1. I saw that contents of the data sheet, what I would like to know is the PSRR for anything other than 10kHz. (especially 2MHz)

　Do you have data available?

2. I got it.

Thanks,

Kaz

Hi Kaz,

I was not able to immediately find this information Let me reach out to the other team members who may have this information, and get back to you with what I can find. One of them is currently out of office so there may be some delay.

Thanks,
Field
