Part Number: ATL431LI-Q1 Other Parts Discussed in Thread: TL431 , ATL431LI Hi Expert,
Customer refer to below example for ATL431LI-Q1 to design a 50mA output capability circuit. But do you have any recommendation for system workarounds to protect…
Part Number: ATL431LI-Q1 Other Parts Discussed in Thread: TLVH431 , LMV431 Hi team,
Is it possible to make output voltage lower than its reference voltage; 2.5Vtyp?

Part Number: TL431LI-Q1 Other Parts Discussed in Thread: TL431LI , ATL431LI , ATL431 Hi team,
May I know what is difference between TL431LIBQDBZRQ1 and ATL431LIBQDBZRQ1?
In ATL431LIBQDBZRQ1, it needs less Ika current 80uA compared with TL431LIBQDBZRQ1…
Part Number: TLV4316 Other Parts Discussed in Thread: TL1431-Q1 , ATL431LI-Q1 , TL431-Q1 , TL431LI-Q1 , TLA431 Tool/software: Hi team,
Do you have alternative of NJM1431AU(TE2), need reference voltage is 2.465V, not P2P is ok.
Thanks

Hello Viknesh, I see why you might be considering this device for short detection as its provides a constant current source. We have an app note that talks about discrete fault detection in the TPS92611-Q1 using the ATL431LI-Q1 as a comparator, however…
Hi Lanxi,
The 0.6mA IKA is related to the output current and going below that minimum would lead to inaccurate voltage regulation. We have our ATL431LI-Q1 shunt regulators that operate at a much lower 80 uA IKA voltage, the oderable part number is ATL431LIAQDBZRQ1…
At the moment, I am interested in the following unencrypted SPICE models:
ATL431LI-Q1
LM78L05
LM317
LM2575
LM2576
LM2596-5.0
LM27313
LP2951_N_5P0
SN74LV123A
TL431
TLC555
TPS7A1601
I may add to this list in the future.
Thank…
Hi John,
I'm glad we were able to figure out the issue! Those waveforms look really good. It would be interesting to see if the 1A device would work with your original component choices, but I don't want to give you too much more work.
There is an…
Hello Yu,
This circuit works roughly as follows:
1: R1 and R2 set the overvoltage threshold. They are sized so that when Vin reaches the desired threshold, the voltage on the ATL431LI ref pin is 2.5V
2. When the voltage on the ref pin is below…
Part Number: ATL432LI-Q1 Other Parts Discussed in Thread: ATL431LI Hi team，
The accuracy range in DS is measured under normal temperature conditions, Ika=1mA. If in circuit design, Ika=0.08~15mA, will the accuracy range change? If so, what is the accuracy…
