Part Number: LM1117 Dear Team,
The customer using LM1117I-5.0 for around 100mA application.
Base on the calculation, the Vin should be higher than 6.3V for 100mA application.
Can we use 5.5Vin as input?
What is the influence of lower than 6.3Vin…
Part Number: LM1117 Hi Team,
I wanted to understand the difference between RθJC(top) and ψJT so I read this article.
http://www.ti.com/lit/an/spra953c/spra953c.pdf
I'd like to confirm if my understanding is correct with you.
Due to the fact that…
Part Number: LM1117 Hi,
My customer is asking me about soldering paste volume.
Does it have any specification or restriction?
e.g.) connecting by solder must be occupy over xx%.
Best Regards, Kuramochi
Part Number: LM1117 Hi,
when using the LM1117DTX-3.3 the datasheet specifies an output capacitor of ESR 0.3ohm to 22ohm.
The ESR of capacitors change significantly with frequency.
Does this ESR apply to any specific frequency range?
The reasoning…
Part Number: LM1117 Hi,
I have questions about the thermal information given in the LM1117 datasheet (SNOS412N) chapter 6.4.
Is it actually true that the DCY package have lower Rjc and Rjb thermal resistance than the NDP package and the other way…
Part Number: LM1117 Hi...
I'd like to know the difference of LM1117 and LM1117I.
I had some operation test at the -30 degree C.
There was a little difference of output voltage deviation and change like as the datasheet.
If there are no problems…
Part Number: LM1117 hi,
I often see application where the voltage regulator is used as a constant current source to drive LED.
In my circuit below, if the MOS switch is always on, a constant 15mA flows through the LEDs.
If I use a PWM signal…
Part Number: LM1117 Other Parts Discussed in Thread: TLV1117 , Hi
There are not the start-up waveforms in datasheet of LM1117 and TLV1117.
If there are the start-up waveforms of these devices,
could you send me them?
Best regards,
Yokot…
Part Number: LM1117 Hello,
I use LM117MPX-5.0 in following conditions:
- Input cap is MLCC 47uF
- Output cap is MLCC 47 uF
- Load current is 200 mA
- Vin is 6.5V
- Vout is 5V (fixed LDO)
The ESR graph for capacitors shows ESR of about 70…
Dear Ryan,
According to your previous statements and as you wrote in case of the TAB that this is not a low impedance connection, we have drawn a simple schematic about the LM1117 Vout connections.
Can you confirm that this is correct?
Can you…
