SI-3120C - 5-Terminal / Multi-Function / Full-Mold / Low Dropout Voltage Dropper

Download the SI-3120C datasheet PDF. This datasheet also covers the SI31 variant, as both devices belong to the same 5-terminal / multi-function / full-mold / low dropout voltage dropper family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • a . D w w w.
  • 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 s.
