ELECTRICAL CHARACTERISTICS Note 4:
ESD (electrostatic discharge) sensitive device. Extensive use of
Note 8:
Dropout voltage is (VIN – VOUT) when VOUT falls to 0.1% below its ESD protection devices are used internal to the LTC1258, however, high nominal value at VIN = VOUT + 0.5V. electrostatic discharge can damage or degrade the device. Use proper ESD
Note 9:
Hysteresis in output voltage is created by package stress that handling precautions. differs depending on whether the IC was previously at a higher or lower
Note 5:
Peak-to-peak noise is measured with a single pole highpass fi lter temperature. Output voltage is always measured at 25°C, but the IC is at 0.1Hz and 2-pole lowpass fi lter at 10Hz. cycled hot or cold before successive measurements. Hysteresis is not
Note 6:
Temperature coeffi cient is the change in output voltage divided by normally a problem for operational temperature excursions where the the nominal output voltage divided by the specifi ed temperature range. instrument might be stored at high or low temperature.
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.
