* When optional ROF is
present pin 5 is No

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. For optional metal case, add suffix ‘-M’ to model number.
6. Output capacitor of 100 µF required to meet quoted ripple & noise.
7. Minimum load of 25% required to meet load regulation & ripple & noise specifications.
8. Operation at no load will not damage device but may not meet all specifications.
9. Pin pitch tolerance: ±0.014 (±0.35), Case tolerance: ±0.02 (±0.5)
