Regulation

Note 1

Thermal resistance of H-package is typically 26 CW ijC 250 CW ijA still air and 94 CW ijA 400 lfmin of air For the Z-package is 60 CW ijC 232 C

W ijA still air and 88 CW ijA at 400 lfmin 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 001 mF be used to limit the high frequency noise bandwidth

Note 3

The temperature coefficient of VOUT is typically within 001% VO C

Note 4

A military RETS specification is available upon request At the time of printing the LM140LA-50 -12 and -15 RETS specifications complied with the Min

and Max limits in this table The LM140LAH-50 LM140LAH-12 and LM140LAH-15 may also be procured as Standard Military Drawings
