2 / 27 page ![]() LE00AB/C SERIES 2/27 Table 1: Absolute Maximum Ratings (*) Our SO-8 package used for Voltage Regulators is modified internally to have pins 2, 3, 6 and 7 electrically communed to the die attach flag. This particular frame decreases the total thermal resistance of the package and increases its ability to dissipate power when an appro- priate area of copper on the printed circuit board is available for heatsinking. The external dimensions are the same as for the standard SO-8. Table 2: Thermal Data Figure 1: Test Circuits Note: If the Inhibit pin is left floating, the regulator is in ON mode. However, to avoid any noise picking-up, it is suggested to ground it when the Inhibit function is not used.
