NAME
FUNCTION
1
1
IN
Regulator Input. Supply voltage ranges from +6.5V to +65V. Bypass with a 10μF capacitor to
GND.
2
2
EN
Enable Input. Force EN high to turn on the regulator. Pull EN low and force
HOLD
high (or
open circuit) to place the device in shutdown mode. Internally connected to ground through a
5M
resistor.
3
3
GND
Ground. GND also functions as a heatsink. Solder to large pads or the circuit-board ground
plane to maximize thermal dissipation.
4
4
RESET
Active-Low Open-Drain Reset Output.
RESET
remains low while V
OUT
is below the reset
threshold or when WDI is not pulsed within 1.6s.
RESET
remains low for the duration of the
reset timeout period after the reset conditions are terminated.
5
5
HOLD
Regulator Hold Input. When
HOLD
is forced low, the regulator stores the on state of the
output allowing the regulator to function even if EN is pulled low. To shutdown the regulator,
release
HOLD
after EN is pulled low. If
HOLD
is unused, either float
HOLD
or connect to OUT.
Internally connected to OUT through a 4μA pullup current source (see Table 1, Truth Table).
6
6
N.C.
No Connection. Not internally connected.
7
—
WDI
Watchdog Timer Input (MAX5023 only). The watchdog timer asserts a reset if WDI does not
transition within the 1.6s watchdog timeout period. WDI
cannot
be disabled.
8
8
OUT
Regulator Output. Fixed (+3.3V or +5V) or adjustable (+2.5V to +11V). Bypass with a 15μF
capacitor (min).
—
7
SET
Feedback Input for Setting the Output Voltage. Connect to GND to set the output voltage to
the preset fixed value (+3.3V or +5V). Connect to an external resistor-divider network for
adjustable output operation (MAX5024 only).
