ENABLE the regulator. ENABLE is internally connected to GND
through a 0.6µA current sink.
Active-Low, Open-Drain/Push-Pull Reset Output.
For the MAX6769/MAX6770, RESET asserts when
RESETIN is below the internal VTH and deasserts when

RESETIN is above the internal VTH threshold.
For all other versions, RESET remains low while OUT is
below the reset threshold. For all versions, RESET
remains low for the duration of the reset timeout period
after the reset conditions end.

Regulator Output. The MAX6765/MAX6766 provide
a fixed output (+1.8V, +2.5V, +3.3V, or +5V). The

+1.8V to +11V. Bypass to GND with a 10µF capacitor
(min).
