MAX5005ACUB+T

Overview

The MAX5005ACUB+T is a fixed-output low-dropout (LDO) voltage regulator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a stable 3.3 V output with a maximum current capacity of 150 mA. The device operates within an input voltage range of 4 V to 5.5 V and features a typical dropout voltage of 300 mV, reaching a maximum of 400 mV at full load. It maintains a voltage regulation accuracy of 3% and draws a quiescent current of 25 µA. Designed for surface-mount assembly in a 10-pin UMAX package, it supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Integrates a 15 kV transient voltage suppressor (TVS) for enhanced protection against electrostatic discharge and electrical overstress events.
• Includes a power-on reset (P) generator that monitors supply voltage levels to ensure proper system initialization.
• Optimized for USB-powered applications with low quiescent current consumption to maximize battery life in portable devices.

Applications

• USB-powered peripheral circuits requiring regulated 3.3 V logic supplies
• Portable electronic devices utilizing battery or USB bus power sources
• Systems requiring integrated ESD protection on power input lines

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube packaging when sourcing. Confirm the 'A' grade designation aligns with required operational temperature ranges. Ensure compatibility with the 10-UMAX/USOP footprint during PCB layout. Cross-reference datasheet revisions to confirm pinout consistency across manufacturing batches.

Selection Notes

Select this component when a fixed 3.3 V output is required alongside integrated ESD protection. The low dropout characteristic suits applications where input voltage closely approaches the output level. Consider the 150 mA limit for load requirements. The integrated reset function simplifies design by removing external monitoring components. Verify thermal dissipation capabilities within the specified operating temperature range.

Part Context

This part belongs to the MAX5005 series of USB LDO regulators. It shares functional similarities with variants like the MAX5005BCUB+ but differs in grading and packaging. The series is designed specifically for USB interfaces, combining regulation, protection, and reset functions in a compact form factor suitable for space-constrained mobile electronics.
