Each input level is equivalent to LS-TTL. Therefore, it may be directly driven by an LS-TTL circuit. *6: A foldback type overcurrent protection circuit is built into the IC regulator (excluding SI-3033C). Therefore, avoid using it for the following applications as it may cause starting errors: (1) Constant current load (2) Plus/minus power (3) Series power (4) VO adjustment by raising ground voltage 40 qSI-3000C Series sElectrical Characteristics Ratings Parameter Input Voltage SI-3000C *1 Output Voltage SI-3000CA Symbol min.
