The 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

60µV

addition to the six available preset output voltages

(1.8V, 2.5V, 2.77V, 2.82V, 3V, and 3.3V), the Dual

Mode™ feature 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 tran-

sistor, the MAX8860 has a low 120µA supply current. An

output fault-detection circuit indicates loss of regulation.

Other features include a 10nA, logic-controlled shut-

down mode, short-circuit and thermal-shutdown protec-

tion, and reverse battery protection. The MAX8860 is

available in a miniature 8-pin µMAX package.
