Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
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 T
readings is subtracted from the highest and the resultant difference is
divided by (T
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 (V

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
V
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.
