TPS7A88: Replacement Part

Part Number: TPS7A88
Other Parts Discussed in Thread: TPS7A91, TPS7A92, TPS7A83A, TPS7A89, TLV752

I am looking for a replacement chip to replace both the TPS7A88 and TPS7A91 since both are out of stock on TI.com. What is the recommendation for chips to replace them both? The x91 is outputting 5V and x88 is outputting 3.3V or 1.8V with a 5V input.

    Hey Elizabeth,

    For TPS7A91 our best replacement would be TPS7A92, however if you need a device in stock I recommend TPS7A8300ARGWT.

    For TPS7A88, I would normally recommend TPS7A89 due to it being pin to pin with higher maximum current. So in this case I recommend TLV75201PDSQT which is also a dual LDO which can have the same outputs you need.
