Note 1:

a.

Input capacitor needed only if Vin>28VDC

Note 2:

a.

The input voltage minus the output voltage should be greater than 3 VDC, if less, a 3% minimum load is

required for proper regulation.

b.

For SR78-1.5S or SR78-1.8S models, Inputs greater than 28VDC require 3% minimum load for proper regulation.
