Other Parts Discussed in Thread: TLVH431, TLV431
Tool/software:
Hello guys,
One of my customers uses TL4051C too like the following tread.
(+) TL4051C: Device behavior with cathode voltage<2.5V - Power management forum - Power management - TI E2E support forums
After PCN, the following sentence is added to the new data sheet (SLOS487A), page 14.
"When the output voltage, VZ, is set below 2.5V on adjustable versions of TL4051,
the device can experience increased reference voltage change with output voltage change (ΔVREF/ΔVKA)
when compared to output voltages set equal to or above 2.5V."
At this moment, my customer has the following questions.
Q1.
How much difference of ΔVREF/ΔVKA between old chip version and new chip version?
Q2.
My customer generates 1.6V using Figure 7-3 adjust shunt regulator too.
What effect does ΔVREF/ΔVKA have on the schematic?
Your reply would be much appreciated,
Best regards,
Kazuya.
