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 2N22…
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 6mA. …
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?
Regards, Ochi
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 ATL…
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…
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 2.5V,…
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 you,
Victor
Part Number: TL431LI-Q1 Other Parts Discussed in Thread: TL431LI , ATL431LI , TL431 , TLV3012-Q1 Dear Ti Community,
For one application, I plan to use the TL431LI part in open-loop mode (for voltage comparison) and, by the way, need to perform many simulations…
Hi Kazuya,
Q1. The boundary itself is marginal in terms of stability, so you want to add some margin to that to account for PVT variations. A good starting point would be to back off the boundary by a factor of 2 for capacitance (if that is what you can…
