Electrical Characteristics
Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.
Note 2: See derating curves for maximum power rating above 25˚C.
Note 3: Unless otherwise specified, T
seen by error amplifier 10 k connected as shown in Figure 1 . Line and load regulation specifications are given for the condition of constant chip temperature. Tem-
perature drifts must be taken into account separately for high dissipation conditions.
Note 4: L
Note 5: Figures in parentheses may be used if R1/R2 divider is placed on opposite input of error amp.
Note 6: Replace R1/R2 in figures with divider shown in Figure 13 .
Note 7: V
Note 8: For metal can applications where V
