Notes:
1. When measuring output ripple, it is recommended
that an external 0.47
µF ceramic capacitor be
placed from the +Vout pin to the -Vout pin.
2. Transient recovery is measured to within a 1% er-
ror band for a load step change of 50 to 100%.
3. Operation at no-load will not damage these units.
However, they may not meet all specifications.
To maintain specified operation, the minimum
output loading given in the table above must be
maintained.
4. It is recommended that a fuse be used on the
input of a power supply for protection. See the
table above for the correct rating.

Mechanical Notes:
• All dimensions are typical in inches (mm)
• Tolerance x.xx = ±0.01 (±0.25)
• Pin 1 is marked by a “dot” or indentation on the side of the unit
• Leads are tin plated for improved solderability.
