1 / 9 page Design Specification 300mA Low Noise Dual LDO PL2211 FEATURES Guaranteed 300mA load/ LDO Ultra low output noise: 100 µV RMS Low ground current: 200 µA Very low dropout: 180mV @300mA Zero shutdown supply current TTL-logic-controlled independent enable input Thermal and current limit protections Low ESR capacitor compatibility to achieve Ultra low droop load transient response Ultra fast line transient response Tiny 10pin 3mm x 3mm MLF (10L-TDLMF ) package Fixed options 1.5V, 1.8V, 2.5V, 2.8V, 3.0V and 3.3V APPLICATIONS Cellular and cordless phones Wireless LAN cards Palmtop computers Personal communication equipment 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. TYPICAL APPLICATION Power IC Ltd. - 1 - www.picsemi.com Version 1.0 Mar 4, 2007 |
