ELECTRICAL CHARACTERISTICS (continued)
(V+ = 5V, I
Note 1: Output voltage guaranteed using preset voltages. See Figures 7a–7d for output current capability versus input voltage.
Note 2: Output voltage line and load regulation depend on external circuit components.
Note 3: For the MAX773, EXT is EXTH and EXTL shorted together.
