NAME

FUNCTION

1

IN

Regulator Input. Bypass IN to GND with a 1μF (min) low-ESR ceramic capacitor.

2

EN

Active-High Enable Input. Force ENABLE high (or connect to IN) to turn the regulator on. Pull

ENABLE low (or leave unconnected) to place the device in a low-power shutdown mode. ENABLE

is internally pulled down to GND through a 0.25μA current sink.

3

SET

Feedback Network Selector. Connect SET to GND when operating the MAX25210 in fixed output

voltage mode (3.3V or 5V) using the internal feedback network. Connect SET to IN or any voltage

higher than 2.4V when an external feedback network (resistive divider) is used, operating the

MAX25210 in adjustable output-voltage mode.

4

RESET

Active-Low, Open-Drain Reset Output. RESET asserts low when OUT is below the reset threshold,

and remains low for the duration of the reset timeout period after the reset conditions end. RESET

also asserts low when ENABLE is low and during thermal shutdown. The pullup voltage on the

RESET pin must be greater than 1.5V.

5

TIMEOUT

Reset-Timeout-Period Adjust Input. Internal capacitance produces a 60μs default delay when

TIMEOUT is left unconnected. Connect a capacitor from TIMEOUT to GND to set a longer timeout

period than default.
