2011. 5. 27 1/9 semiconductor technical data revision no : 1 low noise150ma cmos high performance ldo regulator the kic3211series low dropout linear regulator is ideally suited for portable applications. it offers 1% initial accuracy, extremely-low dropout voltage(220mv at 150ma, 3.0v output type) and low ground current (typically 75ua). designed specifically for handheld and battery-powered devices, the kic3211series provides a ttl-logic-compatible on/off control pin. when disabled, power consumption drops nearly to zero. the kic3211series also works with low-esr ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices. the line transient response and load transient response of the kic3211series are very excellent, thus ics are very suitable for the power supply for hand-held communication equipment. applications h cellular phones,smart phones, pda h battery-powered equipment h laptop, notebook and palmtop computers h consumer/personal electronics features h input voltage range 1.7v to 6.0v h high output accuracy 1.0% accuracy h low dropout 220mv@150ma 3.0v, output type h stability with ceramic output capacitors h high ripple rejection typ. 70db(f=1khz3.0v output type) typ. 60db(f=10khz3.0v output type) h low ground current typ.75 a h quiescent current typ. 0.1 a h excellent line regulation typ. 0.02%/v h built-in fold back protection circuit typ. 50ma@short mode h stability with ceramic output capacitors cin=cout=1.0 ? h ttl-logic-compatible on/off control input dim millimeters a a1 b b1 c d h j k 1.6 0.1 + _ 1.0 0.05 + _ + _ 1.2 0.05 1.6 0.05 + _ 0.5 0.22 0.05 + _ 0.6(max) 0.125 0.05 + _ 0.3 0.05 + _ son1612-6 bk b1 a h a1 c d j c 16 5 4 2 3 1 v in 3 v out 2 gnd 4 nc 5 gnd 6 ce kic3211 series analog cmos integrated circuits mark spec. bnc thwt oli oli lk uhy uhyhwl fta2hhachlw ms gthhta 6ltcult bncanc 6ltcult :t.k mm- a / 1f ?/2
