Description

The SI-3025 is a linear voltage regulator electronic component that falls under the category of Linear Voltage Regulators. It comes in a compact full-mold package that is equivalent to TO220. The regulator has an output current of 0.27A and its low dropout voltage (VDIF) is less than or equal to 0.5V when IO=0.27A. The output ON/OFF control terminal is compatible with LS-TTL, and it can be directly driven by LS-TTL or standard CMOS logic. It also has built-in foldback overcurrent, thermal protection circuits, and a highly accurate overcurrent protection starting current. Moreover, it has a variable output voltage type (SI-3025B) available that can support different settings of VO and VIN.
