TPS7B84-Q1: IQ data

Arie Li

Part Number: TPS7B84-Q1

Hi experts,

May I know whether below plot is for adjustable or fixed 5V part? Customer want to know the IQ difference between TPS7B8401 and TPS7B8450. Do you have that data? What's the value of the internal feedback resistor for the fixed 5V version? Thanks.

Hi Arie,

The plot you have attached here is for the adjustable version of the part, the IQ for the fixed version will be more as it would include the resistor divider which is not included on the datasheet spec, which is specified in the note (2) below the EC table. The difference will be very small as those resistors are in the 30k-300k range. I have asked the designer, and will let you know when they get back to me with those values.

Regards,

John

Hi Arie,

I just heard back from the Designer,

For the 5.0V version the top resistor is 2.175Mohms and the bottom is 325kohms
