Refer to the CALEX Application Notes for the definition of terms, measurement circuits and other information. Noise is measured per CALEX Application Notes. Measurement bandwidth is 0-20 MHz for peak-peak measurements, 10 kHz to 1 MHz for RMS measurements. Output noise is measured with a 0.01µF / 100V ceramic capacitor in parallel with a 1µf / 35V Tantalum capacitor across output pins. Input reflected ripple is measured into a 10µH source impedance. To determine the correct fuse size, see CALEX Application Notes. The Case is tied to the -input pin. Short term stability is specified after a 30 minute warmup at full load, constant line and recording the drift over a 24 hour period. (6) The transient response is specified as the time required to settle from a 50 to 75 % step load change (rise time of step = 2 µSec) to a 1% error band. (7) Dynamic response is the peak overshoot during a transient as defined in note 6 above. (8) The input ripple rejection is specified for DC to 120 Hz ripple with a modulation amplitude of 1% of Vin. (9) The case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated.
