MAX25301 Evaluation Kit
General Description
Quick Start
The MAX25301 evaluation kit (EV kit) evaluates the
MAX25301A/MAX25301B IC family of low noise linear
regulators. The EV kit operates over an input range of
1.7V to 5.5V, provides any output voltage range from 0.6V
to 5.3V, and delivers up to 1A of current. The EV kit comes
with the MAX25301BATB/V+ installed.

Procedure
● Evaluates the MAX25301A/MAX25301B IC in a
The EV kit is fully assembled and tested. To verify board
operation, follow the steps:
10-pin (3mm x 3mm) TDFN
● 1.7V to 5.5V Input Range
Caution:Donotturnonpowersupplyuntilallconnections
are completed.
● 0.6V to 5.3V Resistor-Configurable Output Voltage
(MAX25301B, On Board with Output Set to 3.3V)
1) Verify that jumpers JU101, SELA and SELB are in
their default positions, as shown in Tables 1, 2, and 3.
2) Connect the 5.5V power supply between the IN and
nearest GND terminal posts.
3) Connect the 1A electronic load between the OUT
and nearest GND terminal posts.
4) Connect the DVM between the OUT and nearest
GND terminal posts.
5) Turn on the power supply.
● 1.2V to 5.0V Jumper-Configurable Output Voltage
(MAX25301A, with IC Replacement)
● Up to 1A Output Current
● Proven 2-Layer 1oz Copper PCB Layout
● Demonstrates Compact Solution Size
● Fully Assembled and Tested
6) Enable the electronic load.
7) Verify that the voltage at the OUT terminal post is
approximately 3.3V.

Detailed Description of Hardware
The MAX25301 EV kit evaluates the MAX25301A/
MAX25301B IC family. The MAX25301A/MAX25301B
are low noise linear regulators that deliver 1A of output

The MAX25301 EV kit operates over an input range of
1.7V to 5.5V. The EV kit comes with the MAX25301BATB/
V+ installed and the output voltage is resistor configured
to 3.3V and can deliver 1A of current. The output voltage
on the MAX25301B can be reconfigured to other voltages
from 0.6V to 5.3V by replacing feedback resistors R101
and R102. Refer to the MAX25301 IC data sheet for feed-
back resistor calculation.

ment). See Table 1 for jumper setting of jumper JU101.

DESCRIPTION
SHUNT POSITION
When evaluating the MAX25301B, the Ground Sense
(GS) pin must be connected to ground to stabilize the
output with load. The EV kit provides a jumper SELA to
connect the MAX25301B GS pin to ground. See Table 2
for jumper setting of jumper SELA.

Access signal at the POK test point
The EV kit provides a test point to access the POK output
signal from the MAX25301B. Remove shunt from jumper
SELB to access the MAX25301B POK test point. See
Table 3 for jumper setting of jumper SELB.

Evaluating the MAX25301A
Output Selection (SELA and SELB) for the
MAX25301A
The EV kit provides a set of jumpers SELA and SELB to
configure the output voltage of the MAX25301A, after IC
(U1) replacement. See Table 4 for jumper setting of jump-
ers SELA and SELB.
The EV kit can evaluate the MAX25301A after IC (U1)
replacement. When evaluating the MAX25301A, modify
the EV kit with the following steps:
1) Replace U1 with the MAX25301AATB/V+.
2) Replace R101 with a 0Ω resistor.
3) Remove R102.
4) See Table 4 to configure the MAX25301A
output voltage using jumpers SELA and SELB.
