TPS7A33: Competitor alternative

Part Number: TPS7A33
Other Parts Discussed in Thread: LM337, , TPS7A39, LM2991, UCC284, LM337-N, LM237

Hi team,

do we have anything similar to the LT3081-LT3091?

Other than the TPS7A33/53 and the LM337 family, do we have anything else that has negative Vin and Vout ?

Specifically I would need: -5V5 circa    ->    LIN_REG    ->    -5V @ 2,5..3A    but also a second possibility would be   -3V8 circa    ->    LIN_REG    ->    -3V3 @ 2,5..3A.

This means adjustable output.

Thanks,

Adrian

  • Hi Adrian,

    Thank you for your inquiry.

    Can you clarify your output current requirements? Is it 0.3A?
    If it is lower (like say 150mA) I wanted to quickly highlight a device that does both the +/- rails in a single package: TPS7A39.

    However if your output current is in fact 0.3A, I would like to recommend looking at the following: LM337, LM237, LM337-N, LM2991 & UCC284.

    For further Adjustable + Negative Output recommendations please go here: www.ti.com/.../products.html

  • Hi Wilson,

    no. The output current has to be in the range of 2.5 Ampere, up to 3A.
    I actually did the research on the product folder and came to the conclusion of picking the same devices that you suggested. The limitation that I found though was the current, which peaks at a max of 1.5A in our devices.

    Do we have anything on the roadmap?

  • Hi Adrian,

    No we do have anything currently and we do not share roadmap information on the forums.
