TLV1805-Q1: Alternative part to TLV1805-Q1

Part Number: TLV1805-Q1

Hi there,

I've just finished my design but now this chip is out of stock.

Are there alternatives to this chip?

Kind regards,

Laura

    Hello Laura,

    Unfortunately, the TLV1805-Q1 has a unique pin-out that is not shared with any other devices, including competitors (look closely at the input pin positions), so there is no direct pin-2-pin replacement.

    However, if you are not using the shutdown pin, the TL391 has the same package and pin-out, but it is a open collector output and will require a pull-up, and is not Q1.

    Is it too late to change the design? At several months lead-time, you may want to change.

    What was the main reason for selecting the TLV1805-Q1? Supply voltage?? Output drive?
