*5: Output is ON even when output control terminal V
C
is open. Each input level is equivalent to LS-TTL. Therefore, it may be directly driven by an
LS-TTL circuit.
*6: A foldback type overcurrent protection circuit is built into the I
C
regulator (excluding SI-3033C). Therefore, avoid using it for the following applica-
tions as it may cause starting errors:
(1) Constant current load (2) Plus/minus power (3) Series power (4) V
