Part Number: LM2991 Other Parts Discussed in Thread: TPS7A39 Hi team,
Do we have any negative voltage LDOs that takes -1.5Vin and -0.3Vout? Current is roughly ~100mA, anything above this is ok.
I looked online and the closest I could find was the LM2991…

LM2991 Circuit
We use the above circuit for generating -2.7V from -5V input which is used as the reference voltage for the ADC AD9012. When we have tested this with 274ohms…
Part Number: LM2991QML
We use the above circuit. We are observing ouput oscillations when interfaced with our ADC. Kindly provide a detailed explanation for the follwing.
Implication of using 0.1uF capacitor or any capacitor at the adjust pin. Whether…
Part Number: LM2991 Hello
Output leakage current of LM2991 is changed from 250uA to 150uA in Revision I. However there is no description in the revision history. Which specification is correct?

Part Number: LM46000 Hi! I have been using the LM46000 in combination with LM2991S for a long time, but it's only recently that I have discovered an issue that I cannot explain.
The design consists of the LM46000 in inverting configuration to generate…

Other Parts Discussed in Thread: LM2991 Hi all Would you mind if we ask LM2991? On the datasheet Typical Application P1, in case of not implemented R2（R1=240Ω、Cin=Co=470uF）, this regulator doesn't work as dropper function. So, only this regulator…
Hi Shritesh,
If you want -5Vout from -15Vin, TI does not offer a dedicated negative input/negative output buck converter. You could not use TPS629206. We do offer a negative LDO that you can consider- the LM2991.
Hope this helps,
Thanks,
Nancy
