Line Regulation (LL-36V) (typ.) < SR78-1.5S、SR78-1.8S<±2.5% (at Full Load) SR78-2.5S、SR78-3.3S<±2% (at Full Load) 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. N o t e 3 : N o t e 4 : MECHANICAL DIMENSION ( Top View ) PIN# Single 1 +VIN
