TLV1117LV: P2P device with longer start-up time

Part Number: TLV1117LV
Other Parts Discussed in Thread: TLV1117, LM1117, TLV757P

Hi team,

My customers are using TLV1117LV33DCYT to power CPLD, but TLV1117LV33DCYT start-up time is too short, cannot meet CPLD 200us~2ms requirement. And they already found that CPLD cannot work normally.

So they need a p2p LDO with longer start-up time (200us~2ms). Could you please recommend a suitable part?

    Hi Miranda,

    We don't have too many options in DCY that could meet this requirement. Is customer okay with switching packages?

    If not, then something like LM1117 or TLV1117 may work, but would have to recheck with bench measurements as it is not explicitly said in datasheet.

    If customer is okay with switching package then something like TLV757P could meet this requirement.

    regards,

    Wilson
