Evaluates: MAX25302A/MAX25302B MAX25302 Evaluation Kit General Description Quick Start The MAX25302 evaluation kit (EV kit) evaluates the Required Equipment MAX25302A/MAX25302B IC family of low-noise linear MAX25302 EV kit regulators. The EV kit operates over an input range of 5.5V, 2A DC power supply 1.7V to 5.5V, provides any output voltage range from 0.6V to 5.3V, and delivers up to 2A of current. The EV kit comes Electronic load capable of 2A with the MAX25302AATD/V+ installed. Digital voltmeter (DVM) Features Procedure Evaluates the MAX25302A/MAX25302B IC in a The EV kit is fully assembled and tested. To verify board 10-pin (3mm x 3mm) TDFN operation, follow the steps: 1.7V to 5.5V Input Range Caution: Do not turn on the power supply until all connections are completed. 0.6V to 5.3V Resistor-Configurable Output Voltage (MAX25302B, with IC Replacement) 1) Verify that jumpers JU101, SELA, and SELB are in their default positions, as shown in Tables 1, 2, and 3. 1.2V to 5.0V Jumper-Configurable Output Voltage (MAX25302A, On Board with Output Set to 3.3V) 2) Connect the 5.5V power supply between the IN and nearest GND terminal posts. Up to 2A Output Current 3) Connect the 2A electronic load between the OUT Proven 2-Layer 1oz Copper PCB Layout and nearest GND terminal posts. Demonstrates Compact Solution Size 4) Connect the DVM between the OUT and nearest Fully Assembled and Tested GND terminal posts. 5) Turn on the power supply. 6) Enable the electronic load. Ordering Information appears at end of data sheet. 7) Verify that the voltage at the OUT terminal post is approximately 3.3V.

The MAX25302A/MAX25302B The EV kit provides a set of jumpers SELA and SELB are low noise linear regulators that deliver 2A of output to configure the output voltage of the MAX25302A. See current with only 5.1V of output noise from 10Hz to Table 4 for jumper setting of jumpers SELA and SELB. RMS 100kHz. These regulators require only 100mV of input-to- output headroom at full load. Table 1. EN on MAX25302A/MAX25302B The MAX25302 EV kit operates over an input range (JU101) of 1.7V to 5.5V. The EV kit includes an installed JU101 MAX25302AATD/V+. The output is jumper configurable DESCRIPTION SHUNT POSITION between 1.2V and 5.0V (Table 4) and can deliver 2A of current. 1-2* Enabled. EN = IN 2-3 Disabled.
