NOTES: 1. DPAK Junction–to–Ambient Thermal Resistance is for vertical mounting. Refer to Figure 24 for
board mounted Thermal Resistance.
2. SOP–8 Junction–to–Ambient Thermal Resistance is for minimum recommended pad size. Refer
to Figure 23 for Thermal Resistance variation versus pad size.
3. D2PAK Junction–to–Ambient Thermal Resistance is for vertical mounting. Refer to Figure 25 for
board mounted Thermal Resistance.
4. ESD data available upon request.
