3 / 16 page  Page No. : 3/16 DS‐RS7212‐02 September, 2009 www.Orister.com Absolute Maximum Ratings Parameter Symbol Ratings Units Input Voltage VIN to GND VIN 7.0 V Output Current Limit, I(LIMIT) ILIMIT 0.5 A Junction Temperature TJ +155 oC Thermal Resistance SOT‐25 θ JA 250 oC/W SOT‐25 400 Power Dissipation VSON‐6 (2x2) PD 500 mW Operating Ambient Temperature TOPR ‐40 ~ +125 oC Storage Temperature TSTG ‐55~+150 oC Lead Temperature (soldering, 10sec) ‐ +260 oC NOTES： 1 The power dissipation values are based on the condition that junction temperature TJ and ambient temperature TA difference is 100°C. 2 Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and function operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute‐maximum –rated conditions for extended periods may affect device reliability. 3 The power dissipation of VSON‐6 (2x2) would be 500mW normally with the 0.5X0.5 square inches cooper area connected to the bottom pad. However, it could be up to 1000mW with larger cooper area. Electrical Characteristics (VIN=5V, TA=25°C, unless otherwise specified) Symbol Parameter Conditions Min. Typ. Max.
