*1: Is1 is specified as the 5% drop point of output voltage VO on the condition that VIN = 3.3 V (5 V for SI-3033LSA), and IO = 0.5 A.
*2: Output is OFF when the output control terminal VC is open. Each input level is equivalent to that for LS-TTL. Therefore, it is possible to be
driven directly by an LS-TTL circuit.
The SI-3000LSA series employs a foldback-type overcurrent protection circuit.
*3: In applications in which a certain current is required for start-up, this circuit may cause a start-up error, and therefore the SI-3000LSA series
is not recommended for use in such applications.
(1) Constant current load (2) Dual polarity power supply
(3) Series power supply (4) VO adjustment by raising ground voltage
