*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

The inner frame stage, on which the PTr is mounted,
is directly connected to the VOUT pin.
Therefore, enlarging the copper laminate area
around the VOUT pin is really effective for a heat
radiation.
