Notes
1. Standard pinout is through hole, add suffix ‘-S’ to model number for SMD version.
2. Add suffix ‘-N’ to model number for Remote On/Off negative logic.
3. Noise and ripple measured using 10 µF tantalum and 1 µF ceramic capacitor across the output.

Application Notes
Remote On/Off Control
Standard Remote On/Off logic is positive.
Output ON = >3.5 VDC or open circuit
Output OFF = <1.2 VDC or short circuit
Optional Remote On/Off logic is negative (‘-N’ version).
Output ON = <1.2 VDC or short circuit
Output OFF = >3.5 VDC or open circuit
