2007. 6. 19 1/5 semiconductor technical data revision no : 5 150ma cmos high performance ldo regulator the kic3210t series low dropout linear regulator is ideally suited for portable applications. it offers 1% initial accuracy, extremely-low dropout voltage(135mv at 150ma) and low ground current (typically 90ua). designed specifically for handheld and battery-powered devices, the kic3210t provides a ttl-logic-compatible on/off control pin. when disabled, power consumption drops nearly to zero. the kic3210t also works with low-esr ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices. features input voltage range : 2.7v to 6.0v stability with ceramic output capacitors ultra-low dropout : 135mv @ 150ma high output accuracy : 1.0% accuracy low quiescent current : 90 a ttl-logic-compatible on/off control input zero off-mode current thermal shutdown and current limit protection applications cellular phones,smart phones, pda battery-powered equipment laptop, notebook and palmtop computers consumer/personal electronics dim millimeters a b d e tsv 2.9 0.2 1.6+0.2/-0.1 0.70 0.05 0.4 0.1 2.8+0.2/-0.3 1.9 0.2 0.95 0.16 0.05 0.00-0.10 0.25+0.25/-0.15 c f g h i j k 0.60 l 0.55 a f g g d b e c l h j j i 2 3 15 4 + _ + _ + _ + _ + _ 1 v in 3 on/off control 2 gnd 4 byp 5 v out kic3210t-018 ~ kic3210t-035 cmos linear integrated circuit type name lot no. 123 54 marking
