    Hello, 

    Depending on what you would like there are a couple of alternative options. The TLV75901PDRVR is one option it is similar to the TPS746, but does not have a power good pin. Both parts are in WSON packages with similar pin outs pin 5 would need to be reconnected as it is DNC (do not connect) on the TLV759 and a PG on the TPS746. 

    If you want something similar but with a smaller Iout current range the TPS74501PDRVR is a good option and alternative to the TPS746.
