Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 7:
Thermal regulation is caused by die temperature gradients created of a device may be impaired. by load current or input voltage changes. This effect must be added to
Note 2:
These are high power conditions and are therefore guaranteed normal line or load regulation. only at temperatures equal to or below 70°C. Input is either floating, tied to
Note 8:
Minimum shunt current is measured with shunt voltage held output or held higher than output. 20mV below the value measured at 1mA shunt current.
Note 3:
Output voltage drift is measured using the box method. Output
Note 9:
Minimum input/output voltage is measured by holding input voltage is recorded at TMIN, 25°C and TMAX. The lowest of these three voltage 0.5V above the nominal output voltage, while measuring readings is subtracted from the highest and the resultant difference is VIN – VOUT. divided by (TMAX – TMIN).
Note 10:
RMS noise is measured with a single pole highpass filter at 10Hz
Note 4:
Line regulation and load regulation are measured on a pulse basis and a 2-pole lowpass filter at 1kHz. The resulting output is full-wave with low duty cycle. Effects due to die heating must be taken into account rectified and then integrated for a fixed period, making the final reading an separately. See thermal regulation and application section. average as opposed to RMS. A correction factor of 1.1 is used to convert
Note 5:
Load regulation is measured at a point 1/8" below the base of the from average to RMS, and a second correction of 0.88 is used to correct package with Kelvin contacts. the nonideal bandpass of the filters.
Note 6:
Shunt regulation is measured with the input floating. This
