3 / 15 page Document Number: 70190 S11-0975-Rev. G, 16-May-11 www.vishay.com 3 Vishay Siliconix Si9130 This document is subject to change without notice. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Notes: a. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum. b. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. c. The main switching outputs track the reference voltage. Loading the reference reduces the main outputs slightly according to the closed-loop gain (AVCL) and the reference voltage load-regulation error. AVCL for the 3.3 V supply is unity gain. AVCL for the 5 V supply is 1.54. d. Since the reference uses VL as its supply, its V+ line regulation error is insignificant.
