MAX722CSE+T

Overview

The MAX722CSE+T is a specialized voltage regulator IC designed for palmtop computer applications. It integrates two independent regulators within a single package to manage power distribution efficiently. The device operates with a supply voltage range of 3V to 5V and supports output voltages of 3.3V, 5V, or adjustable configurations. It features surface-mount packaging in a 16-SOIC format with a width of 0.154 inches (3.90mm). The component functions reliably across an operating temperature range of 0°C to +70°C, ensuring stable performance in portable electronic systems requiring precise voltage regulation.

Feature Summary

• Integrates two independent voltage regulators for efficient power management
• Supports flexible output configurations including fixed 3.3V and 5V options
• Designed specifically for low-power palmtop computer applications

Applications

• Palmtop computer power management systems
• Portable electronic devices requiring dual voltage rails
• Battery-powered equipment needing regulated power supplies

Procurement Notes

Verify the exact suffix designation when ordering, as variations may exist between MAX722CSE+T and similar part numbers. Confirm that the 16-SOIC package matches your PCB footprint requirements. Ensure the operating temperature range of 0°C to +70°C aligns with your environmental specifications. Cross-reference the manufacturer's current status for this specific revision to avoid obsolete stock issues during procurement.

Selection Notes

Select this component when a compact solution for dual voltage regulation is required in space-constrained portable designs. It is suitable for applications needing both 3.3V and 5V rails from a single input source. Consider the thermal characteristics and SOIC-16 package size relative to your board layout constraints. Verify compatibility with your system's input voltage range before finalizing the design choice.

Part Context

This part belongs to the Maxim Integrated family of special-purpose regulators tailored for mobile computing. It addresses the need for integrated power solutions in handheld devices where board space is limited. The MAX722 series provides a consolidated approach to voltage regulation compared to using discrete components. It represents a legacy solution for older palmtop architectures still maintained for specific industrial or retro applications.

Replacement Considerations

Check for direct pin-compatible substitutes within the same product family if availability is an issue. Verify that any alternative maintains the dual-regulator architecture and SOIC-16 package dimensions. Ensure electrical parameters such as output voltage accuracy and load regulation meet original design specifications.
