(1)
VO(NOM) is the nominal (typical) regulator output voltage, −5V, −5.2V, −12V or −15V.
(2)
Typicals are at TJ = 25°C and represent the most likely parametric norm.
(3)
Limits are specified and 100% production tested.
(4)
The short circuit current is less than the maximum output current with the
−12V and −15V versions due to internal foldback current
limiting. The
−5V and −5.2V versions, tested with a lower input voltage, does not reach the foldback current limit and therefore conducts
a higher short circuit current level. If the LM2990 output is pulled above ground, the maximum allowed current sunk back into the
LM2990 is 1.5A.
