* When optional ROF is
present pin 5 is No
Connection.
When not present pin 3 &
5 are No Pin.

When not present pin 3 &
5 are No Connection.
1. For dual inline package replace ‘S’ in model number with ‘D’.
2. For optional 3 kV isolation add suffix ‘-H’ to the model number.
3. For dual output delete suffix ‘A’ & split output current equally between rails.
4. For optional Remote On/Off on SIP models, add suffix ‘-R’ to model number.
Applying 5 V via 1 k current limiting resistor and diode turns output off.
5. Output capacitor of 100 µF required to meet quoted ripple & noise.
6. Minimum load of 25% required to meet load regulation & ripple & noise specifications.
7. Operation at no load will not damage device but may not meet all specifications.
8. Pin pitch tolerance: ±0.014 (±0.35), Case tolerance: ±0.02 (±0.5)
9. Weight: SIP 0.009 lbs (4.0 g), DIP 0.013 lbs (6.0 g)
