*1: VIN (max) and IO (max) are restricted by the relation PD = (VIN - VO) × IO.
*2: Set the input voltage to 2.4V or higher when setting the output voltage to 2.0V or lower (SI-3011ZD).
*3: When mounted on glass-epoxy board of 40 × 40mm (copper laminate area 100%).

*1: Set the input voltage to 2.4V or higher when setting the output voltage to 2.0V or lower.
*2: IS1 is specified at the –5% drop point of output voltage VO under the condition of Output Voltage parameter.
*3: Output is OFF when the output control terminal (VC terminal) is open. Each input level is equivalent to LS-TTL level. Therefore, the device can be driven directly by LS-TTLs.
*4: These products cannot be used for the following applications because 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
