MAX15103

Small 3A, Low-Dropout Linear Regulator in a 2.7mm × 1.6mm Package

3A Linear Regulator with Lowest Dropout and Smallest Package on the Market


Please check latest availability status for a specific part variant.

Description

The MAX15103 is a small, low-dropout linear regulator optimized for networking, datacom, and server applications. The regulator delivers up to 3A from a 1.7V to 5.5V input supply with output accuracy of ±1.6%. The output is adjustable down to 0.6V with a guaranteed dropout voltage of less than 200mV at full load. The internal p-channel switch is protected with a foldback current limit and thermal shutdown.

The MAX15103 features an external bypass input to reduce noise. This bypass input also serves as a soft-start control. An enable input and power-good output are included for power sequence control.

The MAX15103 is available in a 1.6mm × 2.7mm WLP package and is fully specified from the -40°C to +85°C operating temperature range.
