Part Number: LM340 Other Parts Discussed in Thread: TPS7B83-Q1 , TPS7A47 Tool/software: Hi all, I am using LM7805MP/NOPB (input voltage +12V) in a design and would like to know if there is any matching part with improved specifications.
The datasheet refers…
Part Number: LM340 Tool/software: We are upgrading an old design which used LM7812CT in a high reliability application. I'd like to keep with this part because it satisfies our new temperature regime which is -40 to +100C. Also we have a long history…
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,
