Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. 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.
DescriptionThe MAX8860 low-noise, low-dropout linear regulator operates from a +2.5V to +6.5V input and is guaranteed to deliver 300mA. Typical output noise for this device is 60VRMS, and typical dropout is 105mV at 200mA. In addition to the six available preset output voltages (+1.8V, +2.5V, +2.77V, +2.82V, +3.0V, and +3.3V), the Dual Mode™ feature of MAX8860 allows the device to be configured as an adjustable output regulator from +1.25V to +6.5V.
Designed with an internal P-channel MOSFET pass transistor,the MAX8860 has a low 120A supply current. An output fault-detection circuit indicates loss of regulation.Other features include a 10nA, logic-controlled shutdown mode, short-circuit and thermal-shutdown protection,and reverse battery protection. The MAX8860 is available in a miniature 8-pin MAX package.
