Part Number: LM1117 Hi...
How about that we use LM1117MP-5.0/NOPB in -32 degree C instead of LM1117IMP-5.0/NOPB.
For example, durability, duty cycle, output votage deviation, output voltage change.etc.
I'd like to know your rapid answer.
Thanks…
Part Number: LM1117 Hello,
Using the LM1117 as an example I want to hear your opinion on this?
I am making sure I meet the LM1117 requirement of 0.3 - 22 ohm ESR on my 22 uF output capacitor and I do the layout as suggested with the shortest and widest…
Part Number: LM1117 For a school project, i need to obtain Label PLd. To do that I have to know MTTF of all my components.
Do anyone know which is MTTF of LM1117-ADJ ?
Thanks
Hi Rony,
You are dissipating 700 mW in order to convert 12 V to 5 V at 100 mA. We can use the Thermal information table for the DCY package to estimate that the junction temperature will be ~43.12 C higher than your ambient temperature (0.7 W x 61.6…
Part Number: LM1117 We ordered a lot LM1117IDT-ADJ about 1000pcs，But we discovered that the die inner the device is produced by STMicroelectronic, I wonder why it is a STMicroelectronics die? by the way,the datacode is JM33AB
Part Number: LM1117 I calculated the junction temperature as follows.
T(junction) = T(ambient) + R(Junction to ambient thermal) * (Vin - Vout) * I(Load)
if T(ambient) is -32c,
and Packaging is SOT-223, than, R(Junction to ambient thermal) is may…
Part Number: LM1117 Hello team,
LM1117 and some of other LDOs is recommending non-ceramic capacitor as output capacitor. Is it only due to circuit stability? If we place dummy resistor, can we use ceramic capacitor without any problem?
Best regards…
Part Number: LM1117 Hi you all, this is Mike
I'm using the LM1117IMP-3.3/NOPB and the output voltage is not 3.3,V, it is 4.4V , the input are 5V I have used this RV before, and I don't remeber to have problems with it,
The pins TWO (the one is in…
