ELECTRICAL CHARACTERISTICS
Note 4: ESD (electrostatic discharge) sensitive device. Extensive use of
ESD protection devices are used internal to the LTC1258, however, high
electrostatic discharge can damage or degrade the device. Use proper ESD
handling precautions.
Note 5: Peak-to-peak noise is measured with a single pole highpass fi lter
at 0.1Hz and 2-pole lowpass fi lter at 10Hz.
Note 6: Temperature coeffi cient is the change in output voltage divided by
the nominal output voltage divided by the specifi ed temperature range.
Note 7: Load regulation is measured on a pulse basis from no load to the
specifi ed load current. Output changes due to die temperature change
must be taken into account separately.

Note 8: Dropout voltage is (V
nominal value at V
Note 9: 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 hot or cold before successive measurements. Hysteresis is not
normally a problem for operational temperature excursions where the
instrument might be stored at high or low temperature.
