qSI-3000B Series
SI-3000B Series
5-Terminal, Multi-Function, Full-Mold, Low Dropout
Voltage Dropper Type
sFeatures
Compact full-mold package (equivalent to TO220) Output current: 0.27A Low dropout
voltage: VDIF≤0.5V (at IO=0.27A) 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, thermal protection circuits Highly accurate overcurent protection starting current SI-3157B : 0.3 to 0.7A (VIN=18V) SI-3025B : 0.3 to 0.7A (When VIN=18V, setting VO=15.7V) 0.3 to 0.75A (When VIN=18V, setting VO=11.7V) Variable output
voltage type (SI-3025B) also available
sApplications
For BS and CS antenna power supplies Electronic equipment
