MAX15101:Small 1A, Low-Dropout Linear Regulator in a 2.7mm × 1.6mm Package

Smallest, 1.7V to 5.5V, 1A LDO (100mV max) on the Market

The MAX15101 is a small, low-dropout linear regulator optimized for networking, datacom, and server applications. The regulator delivers up to 1A 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 100mV at full load. The internal p-channel switch is protected with a foldback current limit and thermal shutdown. The MAX15101 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 MAX15101 is available in a 1.6mm x 2.7mm WLP package and is fully specified from the -40°C to +85°C operating temperature range.
