DESCRIPTION

The PL0501 is a CMOS low dropout linear regulator

with ultra-low-noise output, very low dropout

voltage and very low ground current.

The PL0501 operates from a 2.5V to 5.5V input

voltage range and delivers up to 500mA, with low

dropout of 175mV at 500mA. Other features of the

PL0501 include short-circuit protection and thermal-

shutdown protection.

The PL0501 is designed especially for high powered

portable devices. Its unique CMOS design offers

excellent transient response with very low ground

current.

Other key application areas for the PL0501 include

handheld computers, PCMCIA cards and WLAN

cards.

The PL0501 is available in USP-3L package.
