MAX8563EEE+T

Overview

The MAX8563EEE+T is a dual and triple linear n-FET controller manufactured by Analog Devices under the Maxim Integrated brand. It functions as a low-dropout voltage controller designed for generating multiple power rails from a single input source. The device operates with an input voltage range of 4.5 V to 13.2 V and supports adjustable output voltages between 500 mV and 3.3 V. It provides three independent outputs and consumes a typical operating supply current of 930 uA. The component is housed in a QSOP-16 surface-mount package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates control circuitry for dual or triple linear n-FET configurations to manage multiple voltage rails efficiently.
• Supports adjustable output voltage settings across a wide range, enabling flexible power distribution designs.
• Features low quiescent current consumption to minimize power loss during operation.

Applications

• Generating multiple regulated power supplies in embedded systems
• Power management units requiring simultaneous voltage rail generation
• Industrial control equipment with strict power efficiency requirements

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Ensure packaging integrity remains intact during storage to prevent damage to the QSOP-16 leads. Cross-reference datasheet revisions to confirm pin compatibility with existing board layouts before procurement.

Selection Notes

Select this controller when designing systems requiring multiple linear-regulated outputs driven by external n-FETs. Evaluate thermal dissipation capabilities based on the specified 666.7 mW power dissipation limit. Consider the 4.5 V minimum input voltage constraint against available system power sources. Verify that the required output voltage range falls within the 500 mV to 3.3 V specification limits.

Part Context

This component belongs to the MAX8563 series of low-dropout voltage controllers. It is part of Analog Devices' portfolio of power management integrated circuits designed for efficient voltage regulation. The device utilizes external n-FETs to achieve low dropout performance, distinguishing it from standard fixed-output LDO regulators.
