Pin Description
PIN

NAME
IN
FUNCTION
LDO Input. Connect to a 1.425V to 3.6V input voltage. Bypass with a 22μF ceramic capacitor to GND.
7–11
OUT
LDO Output. Bypass with 2 x 10μF ceramic capacitors to GND. A smaller capacitance can be used if
the maximum load current is less than 4A.
POK
(MAX8556)
Power-OK Output. Open-drain output that pulls low when V
OUT
is outside ±10% of the expected
regulation voltage or when EN is low. POK is high impedance when V
OUT
is within ±10% of the
nominal output voltage. Connect a resistor from POK to a logic supply of less than 3.6V.
12
POR
(MAX8557)
Power-On Reset. Open-drain output goes high impedance 140ms after the output is above 90% of its
nominal regulation voltage. POR pulls low immediately after an output fault or when EN is low.
Connect a resistor from POR to a logic supply of less than 3.6V.
13
FB
Feedback Input. V
FB
is regulated to 0.5V. Connect to the center tap of a resistor-divider from output
to GND to set the desired output voltage.

15
GND
N.C.
Ground
Connect to GND or Leave Unconnected
16
EN
Enable Input. Connect to GND or a logic low to shut down the device. Connect to IN or a logic high
for normal operation.

EP
Exposed Paddle. Connect to GND and to a ground plane for heatsinking.
