DESCRIPTION

The PL0301 is a CMOS low dropout linear regulator

with ultra-low-noise output, very low dropout

voltage and very low ground current.

The PL0301 operates from a 2.5V to 5.5V input

voltage range and delivers up to 300mA, with low

dropout of 160 mV at 300mA. The other features of

PL0301 include short-circuit protection and thermal-

shutdown protection.

The PL0301 is designed especially for battery-

powered portable devices. Its low noise feature

makes PL0301 ideal for noise-sensitive personal

communication applications. Other key application

areas for PL0301 also include palmtop computers,

PCMCIA cards and WLAN cards.

The PL0301 is available in small 5-lead SOT25

package and 3-lead SOT23 with fixed output

voltage versions.
