MAX8563EEE

Overview

The MAX8563EEE is a low-dropout voltage controller manufactured by Analog Devices Inc. under the Maxim Integrated brand. It functions as a dual and triple linear n-FET controller designed for precise power management applications. The device operates within an input voltage range of 4.5 V to 13.2 V, supporting adjustable output voltages from 500 mV to 3.3 V across three independent outputs. It features a quiescent operating current of 930 uA and is rated for commercial temperature ranges between -40 C and +85 C. Packaged in a QSOP-16 surface-mount format, it dissipates up to 666.7 mW.

Feature Summary

• Integrates control circuitry for dual and triple external n-channel FET configurations
• Provides adjustable output voltage regulation capability
• Supports wide input voltage operation suitable for various supply rails

Applications

• Multi-rail power distribution systems requiring precise voltage control
• Embedded systems utilizing external pass elements for high-efficiency regulation
• Industrial equipment needing stable low-dropout performance

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to discontinuation status. Confirm RoHS compliance details via official documentation before integration. Ensure sourcing partners provide valid traceability records. Check for updated EOL notifications regarding availability constraints. Validate package markings against datasheet specifications to prevent counterfeit risks.

Selection Notes

Evaluate thermal dissipation requirements given the 666.7 mW power handling limit in the QSOP-16 package. Compare quiescent current consumption against system standby budgets. Assess compatibility with available external n-FET gate drive capabilities. Consider the adjustable output range flexibility for custom voltage rail generation needs.

Part Context

This component belongs to the MAX8563 series of LDO voltage controllers. It represents a specialized solution for managing multiple power rails using external transistors rather than integrated pass elements. The QSOP-16 packaging offers a compact footprint for dense circuit board layouts while maintaining necessary thermal characteristics for continuous operation.
