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.

NOTES: 1. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
2. The reference voltage on the adjustable device is measured from the output to the adjust pin across R1.
