Original question:

TPS745: Alternate part for TPS74501 with higher current rating

TPS745: Minimum Load Current

Alpha H

Part Number: TPS745

Hi folks, 

I have a question regarding the TPS745. Is there a minimum load current in the datasheet? For example, if I had a 500nA downstream load, is there a minimum threshold I need to meet? 

In terms of current consumption, would the total current consumption be the IQ + 500nA in that scenario?

Thanks,

AH

    Hi AH,

    There is no minimum load requirement for the TPS745.

    The current consumption would be the current required by each pin, summed with the load.  From the datasheet:

    Enable = 10 nA typical
    IQ = 25 uA typical
    PG pin = 300 nA maximum unless you leave it open (you do not use it)
    Load = 500 nA

    Thanks,
