TLV773: SGM2036S pitch

Part Number: TLV773


Tool/software:

Hi team,

can you recommend LDO to P2P replace  SGM2036S(3.3V SOT23-5)? I proposal TLV77333PDBVR, but customer think Iq is too large. Pls help recommend other device which has smaller Iq(<30uA will be better ), and high PSRR.

    Hi Amber,

    TLV70233DBVR could be the alternative here since the IQ sits around 35uA and has high PSRR. Another option with lower IQ, however with higher max Iout, would be TLV75533PDBVR. Both of these would be P2P, below is a quick spec comparison:
