TL1963A: Inconsistent ADJ pin bias current data

Hong Pan

Part Number: TL1963A

In the datasheet, on Page 7, the table says ADJ pin bias current is typically 3uA at 25C, but on page 11, in Figure 19, the curve shows that Iadj is around 1.75uA at 25C. On page 17, the design example uses 3uA. It will probably only change the output voltage by a few mV, but is this a typo?

Hi Hong,

The Electrical Characteristic table (Page 7) data is taken on a larger sample size than the Typical Characteristic curve (Figure 19). As a result we recommend using the Electrical Characteristic table information when doing calculations.

Very Respectfully,
Ryan
