For the Z-package is 60 §C/W ijC, 232 §C/ W ijA still air, and 88 §C/W ijA at 400 lf/min of air. The maximum junction temperature shall not exceed 125 §C on electrical parameters. Note 2: It is recommended that a minimum load capacitor of 0.01 mF be used to limit the high frequency noise bandwidth. Note 3: The temperature coefficient of V OUT is typically within 0.01% V O/§C. Note 4: A military RETS specification is available upon request. At the time of printing, the LM140LA-5.0, -12, and -15 RETS specifications complied with the Min and Max limits in this table. The LM140LAH-5.0, LM140LAH-12, and LM140LAH-15 may also be procured as Standard Military Drawings.
