Characteristic curves are similar for all voltage
options of the LT6660. Curves from the LT6660-2.5 and the LT6660-10 represent the extremes of the voltage options. Characteristic
curves for other output voltages fall between these curves, and can be estimated based on their voltage output.

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: The LT6660 is guaranteed functional over the operating
temperature range of –40°C to 85°C.
Note 3: If the parts are stored outside of the specied temperature range,
the output may shift due to hysteresis.
Note 4: Temperature coefcient is measured by dividing the change in
output voltage by the specied temperature range. Incremental slope is
also measured at 25°C.
Note 5: 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 6: 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. This parameter is not 100% tested.
Note 7: Excludes load regulation errors.
Note 8: Peak-to-peak noise is measured with a single pole highpass lter
at 0.1Hz and 2-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 sec. RMS noise is measured with a single pole highpass lter at
10Hz and a 2-pole lowpass lter at 1kHz. The resulting output is full wave
rectied and then integrated for a xed period, making the nal 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
for the nonideal bandpass of the lters.
Note 9: 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 10: 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 70°C or 0°C 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) hysteresis is not a problem.
