| PIC6117 800mA Ultra-Low Dropout, Ultra-Fast CMOS LDO Regulator FEATURES 800mA high accuracy LDO Output voltage accuracy: 1% Very low dropout: 215mV @ 800mA Zero shutdown supply current TTL-logic-controlled enable input Thermal and current limit protections Ultra low droop load transient response Ultra fast line transient response VDFN-8L 3X3 package The PIC6117 is a CMOS low dropout linear regulator with ultra-low-noise output, very low dropout voltage and very low ground current. The PIC6117 operates from a 2.5V to 5.5V input voltage range and delivers up to 800mA, with low dropout of 215mV at 800mA. Other features of the PIC6117 include short-circuit protection and thermal-shutdown protection. The PIC6117 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 PIC6117 include handheld computers, PCMCIA cards and WLAN cards. The PIC6117 is available in VDFN-8L 3X3 package.
