• Manufacturer Part Number: MAX782
• Description: Triple-Output Power-Supply Controller for Notebook Computers
• Manufacturer: MAXIM [Maxim Integrated Products]

ELECTRICAL CHARACTERISTICS (continued)
(V+ = 15V, GND = PGND = 0V, I
unless otherwise noted.)
Note 1: Output current is further limited by maximum allowable package power dissipation.
Note 2: Since the reference uses VL as its supply, V+ line regulation error is insignificant.
