Overview
GSI-3000C Series SI-3000C Series 5-Terminal, Multi-Function, Full-Mold, Low Dropout Voltage Dropper Type IFeatures • • • • 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 IApplications • For stabilization of the secondary stage of switching power supplies • Electronic equipment IAbsolute Maximum Ratings Parameter DC Input Voltage Voltage of Output Control Terminal DC Output Current Power Dissipation Junction Temperature Ambient Operating Temperature Storage Temperature Thermal Resistance (junction to case) Thermal Resistance (junction to ambient air) Symbol SI-3033C VIN VC IO PD1 PD2 Tj Top Tstg Rth(j-c) Rth(j-a) 20 35 VIN 1.
