NAME
FUNCTION
1
IN
Regulator Supply Input. Supply voltage ranges from 6.5V to 65V. Bypass with a 10µF capacitor to GND.
2E
N
Enable Input. Force EN high to turn on the regulator. Pull EN low to place the device in a low-power
shutdown mode. EN has an internal 5M
Ω
resistor to GND.
3
GND
Ground
4
SET
Feedback Input for Setting the Output Voltage. Connect SET to GND for a fixed 5V output (MAX5084), or
3.3V output (MAX5085). Connect to a resistive divider from OUT to SET to GND to adjust the output
voltage from 2.54V to 11V.
5
OUT_SENSE
Output Voltage Sensing Input. OUT_SENSE is used to Kelvin sense the output voltage in fixed-output
voltage mode. OUT_SENSE can be left floating or connected directly to the load for accurate load
regulation.
6
OUT
Regulator Output. Bypass OUT to GND with a minimum 10µF ceramic capacitor.

EP
Exposed Pad. Connect to GND for heatsinking.
