The
l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C, VIN = VOUT + 0.5V, unless otherwise noted.
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: If the parts are stored outside of the specied temperature range,
the output may shift due to hysteresis.
Note 3: Temperature coefcient is measured by dividing the max change in
output voltage by the specied temperature range.
Note 4: Load regulation is measured on a pulse basis from no load to the
specied load current. Output changes due to die temperature change
must be taken into account separately.
Note 5: Excludes load regulation errors.
Note 6: Peak-to-peak noise is measured with a 3-pole highpass at 0.1Hz
and 4-pole lowpass lter at 10Hz. The unit is enclosed in a still-air
environment to eliminate thermocouple effects on the leads. The test
time is 10 seconds. RMS noise is measured on a spectrum analyzer in
a shielded environment where the intrinsic noise of the instrument is
removed to determine the actual noise of the device.
Note 7: Long term stability typically has a logarithmic characteristic and
therefore, changes after 1000 hours tend to be much smaller than before
that time. Total drift in the second thousand hours is normally less than
one third that of the rst thousand hours with a continuing trend toward
reduced drift with time. Long-term stability will also be affected by
differential stresses between the IC and the board material created during
board assembly.
Note 8: Hysteresis in output voltage is created by package stress that
differs depending on whether the IC was previously at a higher or
lower temperature. Output voltage is always measured at 25°C, but
the IC is cycled to the hot or cold temperature limit before successive
measurements. Hysteresis is roughly proportional to the square of the
temperature change. For instruments that are stored at well controlled
temperatures (within 20 or 30 degrees of operational temperature) it’s
usually not a dominant error source.
