Capacitance

(1)

Typicals are at TJ = TA = 25°C and represent most likely parametric norm.

(2)

Limits are guaranteed to TI's AOQL (Average Outgoing Quality Level).

(3)

The 1µA limit is based on a testing limitation and does not reflect the actual performance of the part. Expect to see a doubling of the

current for every 15°C increase in temperature. For example, the 1nA typical current at 25°C would increase to 16nA at 85°C.

(4)

Source currents are flowing out of the LM26LV/LM26LV-Q1. Sink currents are flowing into the LM26LV/LM26LV-Q1.

(5)

Line regulation (DC) is calculated by subtracting the output voltage at the highest supply voltage from the output voltage at the lowest

supply voltage. The typical DC line regulation specification does not include the output voltage shift discussed in Section 4.3.
