Regulator Input. Supply voltage ranges from 6.5V to 45V. Bypass IN to GND with a low-ESR 47µF
electrolytic capacitor.
Regulator Output. Connect at least a 15µF low-ESR capacitor from OUT to GND.
Regulator Output Feedback Point. OUTSENSE must be connected to OUT for fixed output voltage
versions. Leave OUTSENSE open for adjustable output voltage version.
Ground
Feedback Regulation Set Point. Connect SET to GND for a fixed 3.3V output (MAX5087A) or 5.0V
output (MAX5087B). Connect an external resistive divider network from OUTSENSE to SET to GND to
adjust the output voltage from 2.5V to 11V.
Open-Drain Active-Low Reset Output. Connect a 10kΩ pullup resistor from RESET to any supply
voltage up to 11V to create a logic output.
Reset Timeout Setting Connection. A 2µA charging current is available at CT. Connect a capacitor
from CT to GND to set the reset timeout period (see the Adjustable Reset Timeout Period (CT) section).
Exposed Paddle. Connect externally to a large ground plane to aid heat dissipation. Do not use EP as
a ground connection.
