Part Number: LM1117 Tool/software: Hi,
my question is in regard to thermal resistance data specified on page 4 of the datasheet for LM1117 800-mA, Low-Dropout Linear Regulator. An image is shown below. As you can see for TO-252 package, junction to case…
Part Number: LM1117-Q1 Tool/software: LM1117-Q1 in the specification sheet
The internal protection junction temperature of PLM111750QKVURQ1 is 180 degrees TSD（shutdown）. However, after we received the sample and measured it under different loads, the…
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…
Part Number: LM1117 Tool/software: Component page gives Vin (max) as 15V.
Datasheet 7.1 Absolute Maximum Ratings gives 20V.
7.3 Recommended Operating Conditions gives15V
Questions:
1. what is the actual maximum input rating of this device?
2. Will operation…
Please share a picture of board layout as well as picture of assembled board. The schematic looks acceptable except for R69. What is the purpose of this resistor?
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 Other Parts Discussed in Thread: LP5912 , TPS709 , TPS7B7701-Q1 , TPS7B4256-Q1 , TL1963A , TPS7A45 , TPS706 Hi team,
Does TI have some feature like this? the integrated back-to-back diode of LDO?
Like the below block. SGM2205.
Due to customer…
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.
