The MAX8860 low-noise, low-dropout linear regulator
operates from a +2.5V to +6.5V input and is guaran-
teed to deliver 300mA. Typical output noise for this
device is 60µV
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 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.
