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…

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…
Hi Rongpen,
TI had a change in orderable part number for this device when it was move to meet RoHS. The LM2991S/NOPB is the correct part number.
This has no plans for EOL and is currently active.
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…
HI Simon,
We do not have a spice model for this device. However we have spice models available for many other LDOs. You can use the link below to find a close device that already has a spice model.
Part Number: LM2991 Hello.
One of my customers wants the following data strongly. Please tell me about the following devices.
・LM2991S/NOPB
Could you please tell the amount of characteristic change due to aging if you have.
best regards OZONO…
