SI-3050F Datasheet, PDF (1/6 Pages) Sanken electric – 5-Terminal, Multi-Function, Full-Mold, Low Dropout Voltage Dropper Type

qSI-3000F Series
SI-3000F Series
5-Terminal, Multi-Function, Full-Mold, Low Dropout Voltage Dropper Type
sFeatures
• Compact full-mold package (equivalent to TO220)
• Output current: 1.0A
• Low dropout voltage: VDIF≤1V (at IO=1.0A)
• Variable output voltage (rise only)
May be used for remote sensing (excluding SI-3025F)
• 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, overvoltage, thermal protection circuits
• Variable output voltage type (SI-3025F) also available
sApplications
• For stabilization of the secondary stage of switching power supplies
• Electronic equipment
