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.
