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 150 mV at 300mA. The other features of PL2211 include short-circuit protection and thermalshutdown protection. Its dual channel and low noise feature is ideal for microcontroller and DSP based handheld 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.
