Low-Dropout, 300mA
Linear Regulator in μMAX
General Description
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 RMS , and typical dropout is 105mV at 200mA. In
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.
