DESCRIPTION
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 batterypowered 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.
