SI-3000R Seires
5-Terminal, Multi-Function, Full-Mold, Low Dropout Voltage Dropper Type with Reset Function
■Features
• 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 :VDIF≤1V (at IO=1.5A)
Applicable to battery driven equipment with built-in microcomputer.
• Built-in droping type overcurrent, overvoltage, thermal protection circuits
• Low circuit current ID=typ.1.5mA(IO=0A)
■Applications
• Microcomputer-controlled equipment
• Battery-driven micro-computer-controlled equipment

*1: VIN(max) and IO(max) are restricted by the relation PD(max)=(VIN-VO)•IO=18(W).
*2: Refer to the dropout voltage.(Refer to Setting DC Input Voltage on page 7.)
*3: IS1 is specified at –5(%) drop point of output voltage VO on the condition that VIN=8V, IO=1.0A.
*4: Reset signal output terminal VRST is an open-collector output. Use a pull-up resistor when connecting it to a logic circuit.

*1 C1 : Oscillation prevention capacitor (C1: Approx. 47µF)
The distance between terminals No.5 (VIN) and No.1 (GND)
must be made as short as possible. If the input line is induc-
tive or in the case of long wiring, a capacitor of approxi-
mately 0.33µF with superior high frequency characteristics
must be connected in parallel.Tantalum capacitors are rec-
ommended for C1 and C0, particularly at low temperatures.
