qSI-3000R
Series
SI-3000R Seires
5-Terminal, Multi-Function, Full-Mold, Low Dropout Voltage Dropper Type with Reset Function
sFeatures
• Reset signal output (As the output rises it sends a reset signal to the micro-
computer to secure normal operation of the system. As the output drops a
reset signal is also sent out to protect the system.)
• Reset signal detection output voltage level Voth is 92% of output voltage in
the standard specification. Models with different setting values for different
needs are scheduled to be added to the series.
• Delay time for reset signal can be adjusted freely by external capacitor.
• Compact full-mold package (equivalent to TO220)
• Output current: 1.5A
• Low dropout voltage :V
