I am new to reading measurements in datasheet. I am drawing PCB layout of IC LT1761 for my circuit. What I do not understand is what does REF refer to in the datasheet (attached figure)? As far as I understand pin width is 0.62 mm (max) and length is 1.22 mm. Am I correct? Also what is the length of the IC? Is that 2.9 x 1.4 mm?
Thanks you very much for your kind answer.
