* MANUFACTURERS PART NO. = LM137HVH (NATIONAL SEMICONDUCTOR)
* SUBTYPE: REGULATOR
*
* THIS FILE CONTAINS A PRE-RAD MODEL AT 27 C OF THE LM137HVH THAT WAS
* DEVELOPED UNDER THE GUIDANCE OF GREGORY M. WIERZBA AT
* MICHIGAN STATE UNIVERSITY.
*
* PLEASE NOTE THE FOLLOWING:
*
* 1) THIS MODEL IS TO BE USED FOR ROOM TEMPERATURE SIMULATIONS. THE BUILT-
* IN SPICE TEMPERATURE CORRECTIONS WILL NOT WORK.
* 2) RIPPLE REJECTION, OUTPUT IMPEDANCE, LINE TRANSIENT, AND LOAD
* TRANSIENT RESPONSE ARE MODELED BASED ON LABORATORY
* MEASUREMENTS. THE CORRELATION IS QUITE GOOD. THE SIMULATION VALUES
* ARE WITHIN THE PRODUCT SPEC LIMITS.
* 3) CURRENT LIMITING AND ADJUSTMENT CURRENT BASED ON DATA SHEET
* INFORMATION ARE MODELED ACCURATELY.
* 4) DROPOUT AND POWER UP CHARACTERISTICS HAVE NOT BEEN DEVELOPED YET
* IN THIS MODEL.
* 5) FOR FURTHER DETAILS AND THE MODEL DERIVATION, OBTAIN A COPY OF
* "CA3085, LM7805, LM7812, LM7905, LM137 MACROMODEL DEVELOPMENT" BY G. M.
* WIERZBA DATED 3/25/91.
