*1: IS1 is specified at the 5% drop point of output voltage VO under the condition of Output Voltage parameter.
*2: 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.
*3: Refer to the Dropout Voltage parameter.
*4: VIN (max) and IO (max) are restricted by the relation PD = (VIN - VO) × IO. Please calculate these values referring to the Copper laminate area vs. Power dissipation data.
