Note 1: Power dissipation must be derated at the rate of 3 mW/°C for operation at TA = 25 °C and above.
Note 2: Use the same value for L that was used in the measurement circuit.
Note 3: Output Voltage Variation = (∆VO1/VO1) X 100 (%), ∆VO1 = VO1 (no load) - VO1 (IO = 50 µA).
Note 4: The circuit constants will be changed by the input voltage at the 0.9 V to 2.0 V range and 1.8 V to 10 V range.
