2 / 22 page LM120, LM320-N SNVS756C – APRIL 1998 – REVISED APRIL 2013 www.ti.com 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. ABSOLUTE MAXIMUM RATINGS −5 VOLT REGULATORS (1) (2) (3) Power Dissipation Internally Limited Input Voltage −25V Input-Output Voltage Differential 25V Junction Temperatures (4) Storage Temperature Range −65°C to +150°C Lead Temperature (Soldering, 10 sec.) 300°C Plastic 260°C (1) Refer to RETS120-5H drawing for LM120H-5.0 or RETS120-5K drawing for LM120-5K military specifications. (2) For −5V 3 amp regulators, see LM145 data sheet. (3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. (4) This specification applies over −55°C ≤ TJ ≤ +150°C for the LM120 and 0°C ≤ TJ ≤ +125°C for the LM320-N.

(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. 2 Submit Documentation Feedback Copyright © 1998–2013, Texas Instruments Incorporated Product Folder Links: LM120 LM320-N |
