Quick Start
Recommended Equipment
? MAX15101, MAX15102, or MAX15103 EV kit
? 1.7V to 5.5V, 3A DC power supply
? Load capable of sinking up to 3A
? Digital voltmeter
Procedure
The EV kits are fully assembled and tested. Follow the
steps below to verify the board operation. Caution: Do
not turn on power supply until all connections are
completed.
1) Connect the positive terminal of the 5V supply to the
IN PCB pad and the negative terminal to the nearest
PGND PCB pad.
2) Connect the positive terminal of the load to the OUT
PCB pad and the negative terminal to the nearest
PGND PCB pad.
3) Connect the digital voltmeter across the OUT PCB
pad and the nearest PGND PCB pad.
4) Verify that a shunt is installed on jumper JU1.
5) Turn on the DC power supply.
6) Enable the load.
7) Verify that the voltmeter displays 1.5V.
Detailed Description of Hardware
Regulator Enable (EN)
The MAX15101/MAX15102/MAX15103 feature an enable
input. For normal operation, a shunt should be installed
on jumper JU1. To disable the output, remove the shunt
on JU1 and the EN pin is pulled to GND through resistor

Bypass /Soft-Start Input (SS_BYP)
The MAX15101/MAX15102/MAX15103 utilize an adjust-
able soft-start function to limit inrush current during
startup and reduce the output noise. The soft-start time
is adjusted by the value of C3, the external capacitor
from SS_BYP to GND. By default, C3 is currently 0.1 F F,
which gives a soft-start time of approximately 6.5ms. To
determine the soft-start time, determine t SS using the fol-
lowing formula:
t SS = 6.315 × 10 -5 × C3
where t SS is the required soft-start time in seconds and
C3 is in nanofarads. C3 should be a minimum 4.7nF
capacitor between SS_BYP and GND.
Setting the Output Voltage
The EV kit can be adjusted from 0.6V up to [V IN - 200mV]
by changing the values of resistors R1 and R2. To deter-
mine the value of the resistor-divider, set R2 to 604 I , and
then use the following equation to calculate R1:
/V
where V FB is equal to the 0.6V and V OUT is the output.
R7. See Table 1 for JU1 settings.
