*1: Is1 is specified at 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 LS-TTL level. Therefore, the device can be driven directly by LS-TTLs.  
*3: These products cannot be used in the following applications. Because these applications require a certain current at start-up and so the built-in foldback-type overcurrent  
protection may cause errors during start-up stage.  
(1) Constant current load (2) Positive and negative power supply (3) Series-connected power supply (4) VO adjustment by raising ground voltage
