These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.

(2) 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.
