EVALUATION KIT AVAILABLE MAX15104 Small 2A, Low-Dropout Linear Regulator in a 2.7mm x 1.6mm Package General Description Features The MAX15104 is a small, low-dropout linear regulator 1.7V to 5.5V Operating Range optimized for networking, datacom, and server applica- 150mV Dropout Guaranteed at 2A tions. The regulator delivers up to 2A from a 1.7V to 5.5V 1.6% Output Accuracy Over Line, Load, and input supply with output accuracy of 1.6%. The output Temperature is adjustable down to 0.6V with a guaranteed dropout 70dB PSRR At 500kHz voltage of less than 150mV at full load. The internal p-channel switch is protected with a foldback current limit Adjustable Output from 0.6V to 5.2V and thermal shutdown. Foldback Current Protection The MAX15104 features an external bypass input to Thermal Shutdown Protection reduce noise. This bypass input also serves as a soft- Low Noise 15V (typ) start control. An enable input and power-good output are RMS included for power sequence control.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Note 1: The WLP package is constructed using a unique set of package techniques that impose a limit on the thermal profile. The device can be exposed during board-level solder attach and rework. This limit permits only the use of the solder profiles recommended in the industry-standard specification JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and convection reflow. Preheating is required. Hand or wave soldering is not allowed.
