Part Number: LM340 Other Parts Discussed in Thread: LM1085 i am searching for a lm340T-12 lt spice model, but cant find it on the site
Is this model available anywhere?
Part Number: LM340 Use as a current regulator. National has formula Iout= (V2-3)/R1 and TI has Ipout= V2-3.R1
Which is correct and V2 is not defined anywhere?
Part Number: LM340 For the TO-3 package, on page 1 of the datasheet, it shows Pin1 as Input, Pin2 as Ground, and the case as Ground or Output, so case would be Output
On page 3, it shows the two pins as INPUT and OUTPUT and the case is GROUND
Which is…
Part Number: LM340 In the LM340/LM7812 datasheet ( https://www.ti.com/lit/ds/symlink/lm340.pdf ), the package option addendum has an operating temperature spec. of -40°C to +125°C for the LM7812CT/NOPB, but there is no temperature spec. given for…
Part Number: LM340 Hello;
May I use three zener dioe(Vth:5.1V 5W) to drop input voltage nearly 8V.
What is inrush current of LM7805?
If I use an inductor may I prevent inrush current problem?
Are there any situation which must be pay attention?
Best…
Part Number: LM340 Hi expert,
There ae 4 curves in datasheet Figure.3, customer should use which one when evaluate thermal performance of LM340-15/NOPB?
Regards,
Jared
Part Number: LM340 The datasheet of LM340S-12 says Dropout voltage is 2v, maximum input is 35V.
Can anyone help confirm is it ok if I use it in the circuit input 24V DC, output 12VDC, maximum load current 0.5A, and how to calulate the thermal /temperature…
Part Number: LM340 Hi experts,
We bought these from TI E-Store. There were no notifications of any sort on public domain that TI mixes date-code for your products.
Please confirm:
1. if there's notification letter to share.
2, if these are safe to…
Part Number: LM340 Currently LM340 is listed as "not to be used for new designs" and in its place is LM340A with a suffix of NOPB. What is the meaning of "NOPB"? So far all I have found is that NOPB was used by National Semiconductor…
Part Number: LM340 Hi team,
My customer want to use high accuracy LDO, output accuracy target 1%. I find we only have 2% LDO, such as LM340. Do we have any other option here?
One more question here, can TI LDO get 0.5% accuracy? What limit the output…
