Part Number: LM1117 Tool/software: Dears,
The customer encountered some problems when using LM1117IMPX-3.3. 3.3V is connected to a 500Ω load, +5V is powered by an external power supply, and the external input current is 80mA. Remove 1117, and the external…
hi sir
1: remove the ceramic output capacitor, LM1117 Still output 3.8v in some pcb
2.Green line is current waveform in back of the LM1117
3.used package as below
Part Number: LM1117 Tool/software: Hi team,
Customer use LM1117I, Vin=7V, Vout=5V, Iout=0.6A. They test temperature of the IC case is 70℃， but the Vout decrease to 0 quickly.
I have 2 questions:
Does this trigger over temperature shutdown?
How to calculate…
Hey Zachary,
Thank you for your question. Yes, the "+5" on the end of the date code indicates the extended shelf life of the product. (i.e. YYWW+5 = Date Code +5 years shelf life).
For more information on shelf life please see the product shelf…
Part Number: LM1117 Hi All,
I have a question about LM1117. I would like to dynamically change the output voltage of the LM1117. In that case, we are considering a circuit that uses a transistor to switch the ADJ pin resistance. Is it okay to use the LM1117…
Part Number: LM1117 hello
In the TI COC in the attached file, the DATE CODE is shown as 2341+5. In the case of 2341, I understand it as YYWW, but I am curious about the meaning of +5.

Hello,
We are using LM1117MP-3.3 in one of our design.
The input voltage is 5V and on the path we were earlier using LQM21FN4R7M70L (DCR = 455MOHM) in the design at input and now would like to u…
Part Number: LM1117 Other Parts Discussed in Thread: LM317 Hello, I am using LM1117 for motor controㅣ.
I use Vin = 12V, Vout = 6V.
In the datasheet subject it says
"LM1117 800-mA, Low-Dropout Linear Regulator"
Then Is this LDO is used for…
