EVALUATION KIT AVAILABLE MAX15103 Small 3A, Low-Dropout Linear Regulator in a 2.7mm x 1.6mm Package General Description Features The MAX15103 is a small, low-dropout linear regulator 1.7V to 5.5V Operating Range optimized for networking, datacom, and server applica- 200mV Dropout Guaranteed at 3A tions. The regulator delivers up to 3A 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 Adjustable Output from 0.6V to 5.2V voltage of less than 200mV at full load. The internal p-channel switch is protected with a foldback current limit Foldback Current Protection and thermal shutdown. Thermal Shutdown Protection The MAX15103 features an external bypass input to Low Noise 15V (typ) RMS reduce noise. This bypass input also serves as a softs- Small 1.6mm x 2.7mm WLP Package tart control. An enable input and power-good output are included for power sequence control. The MAX15103 is available in a 1.6mm x 2.7mm WLP package and is fully specified from the -40C to +85C operating temperature range. Applications Ordering Information appears at end of data sheet.

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.
