MAX8515EXK+T

Overview

The MAX8515EXK+T is a low-dropout linear regulator from the Analog Devices/Maxim Integrated family. It operates with an input voltage range of 1.425V to 3.6V and delivers up to 1A of continuous output current. The device features a maximum dropout voltage of 200mV at full load. Output accuracy is guaranteed at ±1.4% over load, line, and temperature variations (0°C to +85°C). It utilizes a P-channel MOSFET pass transistor and requires only 1μF ceramic input and 4.7μF ceramic output capacitors for stability.

Feature Summary

• Features a P-channel MOSFET pass transistor architecture that maintains low quiescent current during heavy loads and dropout conditions.
• Includes logic-controlled shutdown mode, short-circuit protection, and thermal-overload protection for system safety.
• Provides fast transient response capabilities, limiting output voltage deviation significantly during rapid load steps.

Applications

• Servers
• Storage systems
• Networking equipment
• Base stations
• Optical modules

Procurement Notes

Verify the exact part number against official manufacturer documentation before procurement. Confirm package type and pin configuration match design requirements. Check for RoHS compliance status indicated by suffixes. Ensure availability through authorized distributors as supply levels may fluctuate. Validate operating temperature ranges for specific environmental conditions.

Selection Notes

Select this component when high current delivery near the input rail is required. The low dropout characteristic allows operation with minimal headroom. Ceramic capacitor compatibility simplifies board layout. Consider the exposed pad for thermal management in high-power applications. Verify enable pin logic levels align with control signals.

Part Context

This regulator belongs to the MAX8516/MAX8517/MAX8518 series designed for low-input voltage applications. The series shares core architectural features including PMOS pass transistors and similar protection circuits. Variations within the series typically involve additional outputs like Power-OK or Power-On Reset signals. The MAX8515 variant specifically targets general-purpose regulation needs within this parameter set.

Replacement Considerations

Direct replacements include other members of the MAX8516/MAX8517/MAX8518 family depending on required auxiliary features. Verify pin-to-pin compatibility if substituting with different package options. Ensure thermal dissipation capabilities are sufficient for the new application environment.
