These are stress ratings only, and functional 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. ‡ All voltage values are with respect to network terminal ground. DISSIPATION RATING TABLE 1 – FREE-AIR TEMPERATURES PACKAGE AIR FLOW (CFM) TA < 25°C POWER RATING DERATING FACTOR ABOVE TA = 25°C TA = 70°C POWER RATING TA = 85°C POWER RATING D 0 568 mW 5.68 mW/ °C 312 mW 227 mW D 250 904 mW 9.04 mW/ °C 497 mW 361 mW recommended operating conditions MIN MAX UNIT Input voltage, VI§ 2.5 7 V Output current, IO (see Note 1) 0 200 mA Operating virtual junction temperature, TJ (see Note 1) –40 125 °C § To calculate the minimum input voltage for your maximum output current, use the following equation: VI(min) = VO(max) + VDO(max load). NOTE 1: Continuous current and operating junction temperature are limited by internal protection circuitry, but it is not recommended that the device operate under conditions beyond those specified in this table for extended periods of time. |
