Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
ESD (Electrostatic Discharge) sensitive device. Extensive use of may cause permanent damage to the device. Exposure to any Absolute ESD protection devices are used internal to the LT1790, however, high Maximum Rating condition for extended periods may affect device electrostatic discharge can damage or degrade the device. Use proper ESD reliability and lifetime. handling precautions.
Note 2:
The LT1790 is guaranteed functional over the operating
Note 5:
Temperature coefficient is measured by dividing the change in temperature range of –40°C to 125°C. The LT1790-1.25 at 125°C is output voltage by the specified temperature range. Incremental slope is typically less than 2% above the nominal voltage. The other voltage also measured at 25°C. options are typically less than 0.25% above their nominal voltage.
Note 6:
Load regulation is measured on a pulse basis from no load to the
Note 3:
If the part is stored outside of the specified temperature range, the specified load current. Output changes due to die temperature change output voltage may shift due to hysteresis. must be taken into account separately.
