Design Specification
PL2211
DESCRIPTION
The PL2211 is a dual CMOS low dropout linear regulator
with ultra-low-noise output, very low dropout voltage and
very low ground current.
The PL2211 operates from a 2.5V to 5.5V input voltage
range and delivers up to 300mA, with low dropout of 200
mV at 300mA. The other features of PL2211 include short-
circuit protection and thermal-shutdown protection.
The PL2211 is designed especially for battery-powered
portable devices. Its low noise feature makes PL2211 ideal
for noise-sensitive personal communication applications.
Other key application areas for PL2211 also include
palmtop computers, PCMCIA cards and WLAN cards.
The PL2211 has a special feature that if both EN pin is
enabled simultaneously the output of LDO2 delays 20us
from output of LDO1 which helps to minimize inrush
startup current.
The PL2211 is available in tiny 10pin 3mm x 3mm MLF
(10L-TDLMF) package with fixed output voltage versions.
