Part Number: LM2991 Hello team,
My customer would like to know LM2991 Absolute maximum of Vout.
As described in section 7.3.2 of the data sheet, a Schottky diode is clamped at the output to prevent overshoot. When the power supply shuts down, this…

Hello,
My customer is looking for DC/DC products that can be used for the following conditions.
- VIN = -15V, VOUT = -6V, IOUT = about 300mA(typ) : Best…

Hi Experts,
We are seeking your conclusion on this query from customer about design application with LM2991, a negative LDO. They wanted it to convert -6.5Vin to -5.0Vout.
From Section 7.4.1 of the device datasheet:
Does…
Part Number: LM2991 HI,
I have a question of LM2991S, on the Silicon Expert. This device is obsolete.
I find it is still active in your website.
Can you check the lifecycle of LM2991S?
Thanks for your help.
Part Number: LM2991 Hi,
I am using LM2991 with Vin = -5V, Vout = -2V, Iout = 0.3Amax now.
However, to fix the problem, I need to use the LM2991 Vout at -1.55V.
When I refer to the data sheet, Vout is typ -2V, but there is no value for min.
Since…
Part Number: LM2991 Hello guys,
One of my customers decided to use LM2991S/NOPB for their new products and they are routing board pattern of the device for their proto type.
Then they found the deference between 2 type of the device package dimension…
Part Number: LM2991 Hi Team, we would like to know if there is an ESD-CDM value for this device. On the datasheet is it only HBM.
Thank you in advance.

Part Number: LM2991 Hi Team,
We have received a feedback from a customer that he noticed that the description of pin 2 at page 3 of the datasheet (SNVS099I) is "Logic high enable input" while the pin name and drawing show that it is active low. Please…

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…
