Overview
The MAX8719ETA+T is a high-voltage input linear regulator from Analog Devices/Maxim Integrated, designed for low-power applications such as CMOS RAM and real-time clock (RTC) circuits in laptops. It delivers a low quiescent current of 25μA to minimize battery drain during sleep modes. The device operates within a specified voltage range suitable for high-voltage battery systems, providing stable regulation for microcontrollers and memory components.
Feature Summary
- Ultra-low static current consumption optimized for extended battery life in portable devices
- High-voltage input capability compatible with laptop battery architectures
- Integrated design supporting direct powering of RTC and microcontroller logic
Applications
- CMOS RAM power supply in notebook computers
- Real-time clock (RTC) circuit biasing
- Microcontroller standby power management
Procurement Notes
Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm package integrity and marking consistency against official datasheet specifications. Check for RoHS compliance status and manufacturing date codes to ensure compatibility with current assembly processes.
Selection Notes
Select this regulator when ultra-low quiescent current is critical for standby power efficiency. Ensure input voltage ranges match the system's battery profile. Consider thermal dissipation requirements based on load current and ambient temperature conditions during continuous operation.
Part Context
Part of the Maxim Integrated linear regulator portfolio targeting mobile computing platforms. Designed to replace older discrete solutions by integrating regulation and protection features into a compact surface-mount package, reducing board space and component count.
Replacement Considerations
Direct substitutes include MAX8718ETA+T from the same family. Verify pinout compatibility and output voltage settings before substitution. Cross-reference with newer Analog Devices equivalents if long-term availability is required.
