TYPICAL APPLICATION CIRCUIT
PL0501
500mA Low-Dropout
Linear Regulator
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.
