REG2: 300mA Low Noise LDO

REG3: 300mA Low Noise LDO

Independent Enable/Disable Control

Minimal External Components

3×3mm, Thin-DFN (TDFN3×3-10) Package

− Only 0.75mm Height

− RoHS Compliant

Applications

Portable Devices and PDAs

MP3/MP4 Players

Wireless Handhelds

GPS Receivers, etc.

The +0 is a complete, cost effective,

highly-efficient power management solution that

is ideal for a wide range of portable handheld

equipment. This device integrates one PWM

step-down DC/DC converter and two low noise,

low dropout linear regulators (LDOs) in a single,

thin, space-saving package. This device is ideal

for a wide range of portable handheld

equipment that can benefit from the advantages

of technology but does not require a high level

of integration.

REG1 is a fixed-frequency, current-mode PWM

step-down DC/DC converter that is optimized

for high efficiency and is capable of supplying

up to 600mA output current. REG2, REG3 are

low noise, high PSRR linear regulators that are

capable of supplying up to 300mA, and 300mA,

respectively.

The +0 is available in a tiny 3mm × 3mm

10-pin Thin-DFN package that is just 0.75mm

thin.
