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.
