NOTE l: Output or reference voltage temperature coefficients defined as the worst case voltage change divided by the total temperature range. NOTE 2: Unless otherwise specified all limits guaranteed for Tj = 250C, VIN = 6V, IL = 100VA and CL = 1 VF. Additional conditions for the 8-pin versions are feedback tied t0 5V tap and output tied to output sense (Vour = 5V) and VSHurDOWN < 0.8V. NOTE 3: Regulation is measured at constantjunction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are covered under the specification for thermal regulation. NOTE 4: Line regulation for the SPX2954 is tested at IL = 1 mA. NOTE 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured at lV differential. At very low values of programmed output voltage, the minimum input supply voltage of 2V (2.3V over temperature) must be taken into account. NOTE 6: VREF <VOUT S (VIN - 1V), 2.3 SVINS30V, 100VASIL< 250mA, Tj S TJMAX. NOTE 7: Comparator thresholds are expressed in terms of a voltage differential at the feedback terminal below the nominal reference voltage measured at 6V input. To express these thresholds in terms of output voltage change, multiply by the error amplifier gain = VOUTNREF = (R, + R2)/R2. For example, at a programmed output voltage of 5V, the error output is guaranteed to go low when the output drops by 95 mV x 5V/1.235 = 384 mV. Thresholds remain constant as a percent of Vou r as Vou r iS varied, with the dropout warning occurring at typically 5% below nominal, 7.5% guaranteed. NOTE 8: VSHUTDOWN > 2V, VIN < 30V, VOUT =0, Feedback pin tied t0 5V/3.3V Tap.
