Dual, 300mA, Low-Noise Linear Regulator

with Independent Shutdown in UCSP or TDFN

General Description

Features

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

♦ Two Low-Dropout-Voltage Regulators

♦ Low 32µV Output Noise

RMS

♦ 300mA Output Current for Each LDO

♦ 70dB PSRR at 10kHz

32µV

, and PSRR is 70dB at 10kHz. Designed with

RMS

♦ Independent Shutdown Controls

♦ Low 60mV Dropout at 100mA Load

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.

♦ 115µA Operating Supply Current per LDO

♦ 1.5V to 3.3V Factory-Preset Output

♦ Small Ceramic Output Capacitors

♦ Output Current Limit

♦ Thermal-Overload and Short-Circuit Protection

♦ 1.95W Power-Dissipation Capability (TDFN)

♦ 2mm²Footprint (UCSP)

Applications

Cellular and Cordless Phones

PDAs and Palmtop Computers
