This specification applies over

−55°C ≤ TJ ≤ +150°C for the LM120 and 0°C ≤ TJ ≤ +125°C for the LM320-N.

(3)

Regulation is measured at constant junction temperature. Changes in output voltage due to heating effects must be taken into account

separately. To ensure constant junction temperature, low duty cycle, pulse testing is used. The LM120/LM320-N series does have low

thermal feedback, improving line and load regulation. On all other tests, even though power dissipation is internally limited, electrical

specifications apply only up to PD.

(4)

This specification applies over

−55°C ≤ TJ ≤ +150°C for the LM120 and 0°C ≤ TJ ≤ +125°C for the LM320-N.

(5)

Thermal resistance of typically 85°C/W (in 400 linear feet air flow), 224°C/W (in static air) junction to ambient, of typically 21°C/W

junction to case.
