Analog Devices Inc./Maxim Integrated MAX25302EVKIT#

Overview

MAX25302EVKIT# from Analog Devices is a fully assembled and tested evaluation kit designed to characterize the MAX25302A and MAX25302B 2A low-noise linear regulators. It supports input voltages from 1.7V to 5.5V, delivers up to 2A output current, features jumper-configurable output (1.2V–5.0V for MAX25302A), and includes the pre-installed MAX25302AATD/V+ in a 3mm × 3mm 10-pin TDFN package.

For engineers reviewing the MAX25302EVKIT# datasheet, MAX25302EVKIT# pinout, MAX25302EVKIT# application, or MAX25302EVKIT# equivalent, this kit enables rapid validation of low-noise LDO performance in automotive and industrial power rails-particularly where <5.1µVRMS noise (10Hz–100kHz), <100mV dropout at full load, and compact 2-layer PCB layout are critical selection criteria.

Technical Context

The MAX25302EVKIT# implements a proven 2-layer, 1oz copper PCB layout optimized for low-noise LDO evaluation. It provides direct access to EN, GS, and POK signals via configurable jumpers (JU101, SELA, SELB) and terminal posts for IN, OUT, and GND-enabling both functional verification and parametric testing under real load conditions.

Hardware flexibility includes on-board output voltage selection for MAX25302A (via SELA/SELB jumpers per Table 4) and support for MAX25302B evaluation through IC replacement and external feedback resistors (R101/R102), accommodating resistor-configurable outputs from 0.6V to 5.3V while maintaining thermal and EMI integrity.

FAQ

What ICs does the MAX25302EVKIT# evaluate?

The MAX25302EVKIT# evaluates the MAX25302A and MAX25302B 2A low-noise linear regulators. It ships with the MAX25302AATD/V+ pre-installed and supports MAX25302B evaluation via IC replacement and external feedback resistors. Both variants share identical 10-pin TDFN packaging and core specifications including 5.1µVRMS output noise and ≤100mV dropout at full load.

How is output voltage configured on the MAX25302EVKIT#?

For the pre-installed MAX25302A, output voltage is set via jumpers SELA and SELB per Table 4 (e.g., 3.3V default). For MAX25302B evaluation, the IC must be replaced with MAX25302BATD/V+, and output is resistor-configured using R101/R102 to achieve 0.6V–5.3V-calculations follow the MAX25302 datasheet's feedback network equations.

Does the MAX25302EVKIT# require external components to operate?

No-the MAX25302EVKIT# is fully assembled and tested with all required passives, jumpers, and the MAX25302AATD/V+. Only a 5.5V/2A DC power supply, 2A electronic load, and DVM are needed for basic operation. Jumper configurations (JU101, SELA, SELB) determine EN enable state, GS grounding (for MAX25302B), and POK test point access.

What is the PCB layout architecture of the MAX25302EVKIT#?

The MAX25302EVKIT# uses a proven 2-layer, 1oz copper PCB layout optimized for low-noise LDO evaluation. It features dedicated IN/OUT/GND terminal posts, thermal relief pads for the IC's EP, and controlled trace routing to minimize ground bounce and EMI-demonstrating a compact solution size suitable for space-constrained automotive and industrial designs.

Can the MAX25302EVKIT# validate POK functionality?

Yes-the MAX25302EVKIT# provides access to the MAX25302B's POK (Power-OK) signal via jumper SELB: removing the shunt exposes the POK test point. This allows engineers to verify power-good timing, threshold accuracy, and response to load transients directly during MAX25302B evaluation-confirming system-level power sequencing compliance.
