OUT -0.3 ~ +6.6 V LX and CE -0.3 ~ +6.6 V Maximum Junction Temperature +150 °C Storage Temperature Range -65 ~ +150 °C Lead Temperature (Soldering 10sec) +260 °C Human Body Mode 8000 V ESD Susceptibility Machine Mode 500 V SOT89 200 Junction-to-Ambient Thermal Resistance, θ SOT23 250 °C/W JA SOT23-5 250 SOT89 0.625 Power Dissipation, PD SOT23 0.5 W SOT23-5 0.5
Recommended Operating Ratings Parameter Value Unit
VIN 0.85 ~ 6.00 V Operating Temperature Range -40 ~ +85 °C Note that Absolute Maximum Ratings indicate limitations beyond which damage to the device may occur. Recommended Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specified performance limits.
