Wide range of preset output voltage options are available. These ultra-low dropout linear regulators respond fast to step changes in load which makes them suitable for low voltage micro-processor applications. The TJ4230 is developed on a CMOS process technology which allows low quiescent current operation independent of output load current. This CMOS process also allows the TJ4230 to operate under extremely low dropout conditions. X.X = Output Voltage = 1.0, 1.2, 1.8, 2.5, and 3.3 Absolute Maximum Ratings CHARACTERISTIC SYMBOL MIN. MAX. UNIT Input Supply Voltage (Survival) VIN - 6.5 V Enable Input Voltage (Survival) VEN - 6.5 V Maximum Output Current IMAX - 3 A Lead Temperature (Soldering, 5 sec) TSOL 260 ºC Storage Temperature Range TSTG -65 150 ºC Operating Junction Temperature Range TJOPR -40 125 ºC Package Thermal Resistance * ΘJA-SOP8-PP 68 ºC/W * Calculated from package in still air, mounted to 2.6mm X 3.5mm(minimum foot print) 2 layer PCB without thermal vias per JESD51 standards. |
