NAME FUNCTION
1111 1IN
Regulator Input. Bypass IN to GND with a capacitor
with a minimum value of 0.1µF.
2 2 2 2 2 GND Ground
3 3 3 — 3 ENABLE
Active-High Enable Input. Drive ENABLE high to turn
on the regulator. ENABLE is internally connected to
GND through a 0.6µA current sink.
4555 5RESET
Active-Low, Open-Drain/Push-Pull Reset Output.
For the MAX6769/MAX6770, RESET asserts when
RESETIN is below the internal V
TH
and deasserts
when RESETIN is above the internal V
TH
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.
5 7 7 7 7 TIMEOUT
Reset Timeout Adjust Input. Connect TIMEOUT to
OUT for the internally fixed timeout period. For an
adjustable timeout, connect a capacitor from
TIMEOUT to GND. See the Selecting Timeout
Capacitor section.
6 8 8 8 8 OUT
Regulator Output. The MAX6765/MAX6766 provide
a fixed output (+1.8V, +2.5V, +3.3V, or +5V). The
MAX6767–MAX6774 provide a fixed output voltage
of +1.8V, +2.5V, +3.3V, or 5V, or adjust the output
from +1.8V to +11V. Bypass to GND with a 10µF
capacitor (min).
