Note 1: Power dissipation is 600 mW when mounted as recommended. Derate at 4.8 mW/°C for operation above 25 °C.
Note 2: Power dissipation is 1000 mW when mounted as recommended. Derate at 8 mW/°C for operation above 25 °C
Note 3: Power dissipation is 950 mW when mounted as recommended. Derate at 7.6 mW/ °C for operation above 25 °C.
Note 4: Device is connected as an inverter, with pins 1, 6, and 7 unconnected; CIN = 2.2 µF tantalum, COUT = 33 µF tantalum.
Note 5: Output resistance means the slope of the ∆VOUT vs. ∆IOUT curve, for output currents of 1 to 20 mA. This represents a linear approximation
of the curve.
Note 6: Device is connected as a positive to negative converter/regulator with R1 = 44.2 k, R2 = 154 k, C1 = 4.7 nF, CVIN = 4.7 µF tantalum,
CIN = 2.2 µF tantalum, COUT = 33 µF tantalum.
