SI-3000C Series
5-Terminal, Multi-Function, Full-Mold, Low Dropout Voltage Dropper Type
sFeatures
• • • • Compact full-mold package (equivalent to TO220) Output current: 1.5A Low dropout voltage: VDIF≤1V (at IO=1.5A) Variable output voltage (rise only) May be used for remote sensing • Output ON/OFF control terminal is compatible with LS-TTL. (It may be directly driven by LS-TTL or standard CMOS logic.) • Built-in foldback overcurrent (SI-3033C: Drooping type overcurrent), overvoltage, thermal protection circuits
sApplications
• For stabilization of the secondary stage of switching power supplies • Electronic equipment

*1: "A" may be indicated to the right of the Sanken logo. *2: VIN(max) and IO(max) are restricted by the relation PD(max)=(VIN-VO)•IO=18(W). *3: Refer to the dropout voltage.(Refer to Setting DC Input Voltage on page 7.) *4: IS1 is specified at –5(%) drop point of output voltage VO on the condition that VIN=VO+3V, IO=0.5A. *5: Output is ON even when output control terminal VC is open. 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
