The PL0300/P is a CMOS low dropout linear
regulator with ultra-low-noise output, very low
dropout voltage and very low ground current.
The PL0300/P operates from a 2.5V to 5.5V input
voltage range and delivers up to 300mA, with low
dropout of 380mV at 300mA. Other features of the
PL0300/P include short-circuit protection and
thermal-shutdown protection.
The PL0300/P is designed especially for battery-
powered portable devices. Its reference bypass pin
improves low noise performance which makes it
ideal for noise-sensitive RF and personal
communication applications. Other key application
areas for the PL0300/P include handheld
computers, PCMCIA cards and WLAN cards.
The PL0300/P is available in small 5-lead SOT-25
package.
