Thermal Resistance
Junction to Case
Junction to Ambient
Note 10: This specification applies over −55°C
Note 11: 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 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 P
Note 12: Thermal resistance of typically 85°C/W (in 400 linear feet/min air flow), 224°C/W (in static air) junction to ambient, of typically 21°C/W junction to case.
Note 13: Refer to RETS120-15H drawing for LM120H-15 or RETS120-15K drawing for LM120K-15 military specifications.
