TLV1117: Searching TI solution

Part Number: TLV1117
Other Parts Discussed in Thread: TPS7A20

Hi Team,

Would like to ask if the following REGULATOR has a smaller package that can be recommended? (SOT89?)
TLV1117-33IDCYR 800MA 3.3V SOT-223 SMD

    Hi Kygo,

    TLV1117 does not come in SOT-89, its smallest package option would be an SON 4mm x 4mm. 

    I could provide you another alternative LDO, but I would need some more information:

    1. What is your input voltage?

    2. What is your output current? 

    3. What are the important parameters? (PSRR, Iq, noise, etc.)

    4. Do you need the package to have leads?

    Regards,

    Andres

    Hi Andres

    Thank you for the support !

    1. What is your input voltage? 5
    2. What is your output current? At least 300mA
    3. What are the important parameters? (PSRR, Iq, noise, etc.) noise
    4. Do you need the package to have leads? Smaller than SOT223
