Dual, 300mA, Low-Noise Linear Regulator
with Independent Shutdown in UCSP or TDFN
General Description
The MAX8559 dual, low-noise, low-dropout (LDO) linear
regulator operates from a 2.5V to 6.5V input voltage
and delivers at least 300mA of continuous output cur-
rent. It offers low output noise and low dropout of only
60mV at 100mA. Typical output noise for this device is
32µV
RMS
, and PSRR is 70dB at 10kHz. Designed with
an internal P-channel MOSFET pass transistor, the
MAX8559 maintains a low 115µA supply current per
LDO, independent of the load current and dropout volt-
age. Other features include short-circuit protection and
thermal-shutdown protection. The MAX8559 includes
two independent logic-controlled shutdown inputs and
is capable of operating without a bypass capacitor to
further reduce total solution size. The MAX8559 is avail-
able in a miniature 8-bump UCSP (2mm x 1mm) or
8-pin TDFN (3mm x 3mm) package.
