- External Capacitors
C1=100uF20WVx2pcs or more (Recommended OS-CON SH, FA type)
C2=220uF10WVx2pce or more (Recommended OS-CON SH, FA type)
- ON/OFF Control
ON/OFF control is controlled by opening and shortening between 5pin(ON/OFF)
and 3, 4pin (-Vin)
- Adjustable Output Voltage
The output voltage is adjustable by connecting a resistor between
14pin (V.ADJ) and 17, 18pin(+Vout).When 14pin is open, the following rating
voltage is output.
BSI-3.3S = +3.3V±5%
BSI-5.0S = +5.0V±5%
