MAX1727EUG

Overview

The MAX1727EUG is a Power Management IC (PMIC) designed for GSM cellular and PCN handset applications. It integrates four low-noise LDO regulators, including R1OUT at 2.90V/100mA. The device operates within an input voltage range up to 5.5V and supports surface mount installation in TSSOP-24 packages. It functions across a temperature range of -40°C to +85°C with a current supply of 1.8mA.

Feature Summary

• Integrates four low-noise LDO regulators for efficient power distribution
• Includes short circuit protection, thermal shutdown, and enable control
• Features input under-voltage protection and noise bypass terminals

Applications

• GSM cellular phone power management
• PCN handset RF power systems
• Portable mobile communication devices

Procurement Notes

Verify the specific suffix and package variant against the official datasheet before ordering. Confirm availability status as supply may be limited or restricted. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit risks.

Selection Notes

Select this PMIC for GSM and PCN handset designs requiring integrated low-noise regulation. Evaluate the 2.90V output capability against load requirements. Consider the TSSOP-24 footprint for PCB layout constraints. Verify thermal performance within the specified operating temperature range.

Part Context

The MAX1727EUG belongs to the Maxim Integrated PMIC family targeting mobile communications. It consolidates multiple regulator functions into a single chip to reduce board space. This integration supports the miniaturization trends in early GSM and PCN handset architectures.

Replacement Considerations

Check for direct pin-compatible substitutes within the same product family. Verify that alternative components support identical voltage levels and current ratings. Ensure interface compatibility and thermal characteristics match the original design specifications.
