Part Number: TLVH431 Other Parts Discussed in Thread: TINA-TI , TLV431 , , LMV431 Tool/software: TINA-TI or Spice Models Hi,
several weeks ago in February I reported some problems with the SPICE models of the shunt regulators TLVH431, TLV431 and LMV431. …
Part Number: LMV431 Other Parts Discussed in Thread: TLV431 Hi,
As I'm doing both a noise sensitive and power sensitive design, I plan to run the LMV431 at considerably lower current than 1 mA. I can not find any literature specifying how noise is effected…
Hello,
It is the TLV431 that's giving me trouble (Left oscillogram is the LMV431, right oscillogram is the TLV431).
For variants like LMV431 or TLVH431, I haven't seen any problems.
Thank you,
Thibaud
Part Number: LMV431 Other Parts Discussed in Thread: TL431 , Hi developers,
I'm using this circuit in my compensator.
Do you have reference to this circuit using a UCC2897 component? I'm have difficult with transfer function and my PSU is unstable at…
Part Number: LMV431 Other Parts Discussed in Thread: LM25085 , TL431 , TLV431 , , LM321
Hello,
We would to use TL431 (TL431ACDBZR) instead of LMV431A in the attached schematic for current limit circuit as noted in blue added to LM25085. can you please advice…
Part Number: LMV431A Other Parts Discussed in Thread: LMV431 Hello, We're trying to create an AC voltage detect circuit using the LMV431, but are seeing considerable hysteresis in PSPICE simulation.
We would like to see is the RED trace go low when the…
I got 43.3V and different kind of damaged waveform on SW node:
Voltage on the REF pin of LMV431 is 2.18V, on the anode of the LMV431 is 1V and 0.5V on FB pin.
Perhaps I am misunderstanding how the LMV431 works.
Looking at the datasheet functional diagram, it seems to me that the NPN output would be in saturation or active mode if Ref is above 1.24V.
If this were the case then it would essentially be a short…
Other Parts Discussed in Thread: LMV431 , TL431 Can I use LMV431 as single supply comparator like fig.18 of TL431 datasheet ?
I would realize a POWERGOOD signal with very low current consumption : TL431 needs 1mA of bias current, while LMV431 needs only…
Part Number: LM5023 Other Parts Discussed in Thread: TL432 , LMV431 , , ATL432 In the schematic diagram,(12V 5A), using the TL432, regulation is suitable up to 12V 2A; after that, the voltage drops significantly. Replacing the TL432 with LMV431, the regulation…
