Other Parts Discussed in Thread: TPS719, TPS7A90

Hi Sir,

 

My customer would like design LDO on SDI application.

Would you please provide recommendation p2p solution for this?

MM3816A18RRE(R59-AX90)   1PCS/PCBA

MM3816A25RRE(R59-AX97) 3PCS/PCBA

MM3816A33RRE(R59-AY06) 8PCS/PCBA

 

BR,

    Hi SHH,

    Can you share the pinout and details of this part? Meaning the input voltage range, load current range, and any other notable features? I can not find this datasheet online. 

    That would help me to recommend a viable p2p solution.

    Thanks,

    Please check whether TPS719 is the best solution, since the dropout voltage is slightly different.

    Does TI has other p2p solutions?

    Hi John,

    I mailed the datasheet to you. Please provide suggestions on the replacement.

    HI SHH,

    A p2p for the MM3816 could be the TP7A03. Even though this is a low IQ LDO, it does have a phenomenal load transient response. Another option could be the TLV740. Both are Pp2p.

    We don't have p2p for the MM176 but the TPS7A90 could be a good recommendation. This is a much lower noise regulator which can help minimize jitter.  If they are looking for dual LDO's to save space the TPS7A87 uses the same technology as the TPS7A90 but has two independent outputs and inputs in the same package.  These may also an option instead of the XC6222.

    Let me know what you think.
