Note 2: These are high power conditions and are therefore guaranteed only at temperatures equal to or below 70°C. Input is either floating, tied to output or held higher than output. Note 3: Output voltage drift is measured using the box method. Output voltage is recorded at TMIN, 25°C and TMAX. The lowest of these three readings is subtracted from the highest and the resultant difference is divided by (TMAX – TMIN). Note 4: Line regulation and load regulation are measured on a pulse basis with low duty cycle. Effects due to die heating must be taken into account separately. See thermal regulation and application section. Note 5: Load regulation is measured at a point 1/8" below the base of the package with Kelvin contacts. Note 6: Shunt regulation is measured with the input floating. This parameter is also guaranteed with the input connected (VIN – VOUT) > 1V, 0mA ≤ ISINK ≤ 10mA. Shunt and sink current flow into the output. Note 7: Thermal regulation is caused by die temperature gradients created by load current or input voltage changes. This effect must be added to normal line or load regulation. Note 8: Minimum shunt current is measured with shunt voltage held 20mV below the value measured at 1mA shunt current. Note 9: Minimum input/output voltage is measured by holding input voltage 0.5V above the nominal output voltage, while measuring VIN – VOUT. Note 10: RMS noise is measured with a single pole highpass filter at 10Hz and a 2-pole lowpass filter at 1kHz. The resulting output is full-wave rectified and then integrated for a fixed period, making the final reading an average as opposed to RMS. A correction factor of 1.1 is used to convert from average to RMS, and a second correction of 0.88 is used to correct the nonideal bandpass of the filters. Note 11: If the part is stored outside of the specified temperature range, the output may shift due to hysteresis. ELECTRICAL C C HARA TERISTICS The ● denotes specifications which apply over the full operating temperature range, otherwise specifications are TA = 25°C. VIN = 15V, IOUT = 0 unless otherwise noted. |
