Output current tolerance values are given based on C
1.33 is typical for high volume production. A value of 1.5 is generally considered to
indicate a 6 sigma process (allowing for a 1.5 sigma drift from the mean with a
C
For reference Table 7 shows the expected PPM fallout rate for a given C
The data in Table 6 shows that the design meets the +/-7% target specification with a C
of >1.33. In additional the design is capable of meeting a tolerance specification of < +/-
5% at low line.
