MAX8711ETE

Overview

The MAX8711ETE is a low-cost, linear-regulator LCD panel power supply manufactured by Analog Devices Inc./Maxim Integrated. It belongs to the MAX8710-MAX8761 series and is designed for board-level voltage-conversion applications. The device provides stable output voltages suitable for powering local negative supplies from positive logic sources. It features high efficiency and low operating current, making it ideal for battery-powered equipment and portable instruments. The component utilizes a compact surface-mount package to minimize PCB footprint while maintaining reliable performance in consumer electronics and medical devices.

Feature Summary

• Provides regulated output voltage for LCD panel biasing
• Operates with low quiescent current for battery efficiency
• Requires minimal external components for implementation
• Supports shutdown control for power management

Applications

• Local negative supply generation from positive logic rails
• Powering small LCD panels in portable devices
• Battery-operated handheld terminals and PDAs
• Medical instrument power regulation

Procurement Notes

Verify authenticity through authorized Analog Devices channels due to Maxim's acquisition history. Confirm package integrity and RoHS compliance upon receipt. Check for obsolescence notices as legacy Maxim products may have limited availability. Ensure ESD precautions are followed during handling. Validate part markings against official datasheet specifications to prevent counterfeit infiltration.

Selection Notes

Select this regulator when designing circuits requiring a stable negative or specific positive voltage derived from a higher logic supply. Consider thermal dissipation requirements based on load current and input-output differential. Evaluate space constraints as the ETE package offers a compact solution. Compare against switching alternatives if higher efficiency at larger current loads is required. Verify compatibility with system ground references and noise sensitivity of connected LCD drivers.

Part Context

This component falls under the Maxim Integrated portfolio, now integrated into Analog Devices following the 2021 merger. The MAX871x series represents a family of linear regulators optimized for display biasing. These parts bridge the gap between complex switching converters and simple LDOs, offering a balance of cost, size, and performance for mid-range power needs in portable electronics.

Replacement Considerations

Public confirmed substitute part numbers: MAX8710ETE+, MAX8712ETE+. Verify pinout compatibility and output voltage tolerance before substitution. Ensure thermal characteristics match the original design constraints.
