ELECTRICAL CHARACTERISTICS (continued)
(V
DCIN
= 18V, internal reference, 1μF capacitor at REF, 1μF capacitor at VL,
T
A
= 0°C to +85°C
, unless otherwise noted. Typical values
are at T
A
= +25°C, unless otherwise noted.)
CONDITIONS
PARAMETER
ERROR AMPLIFIERS
Note 1:
When DCIN is less than 4V, VL is less than 3.2V, causing the battery current to be typically 2μA (CS plus BATT input
current).
