2007. 3. 19 1/6 semiconductor technical data kr15s018m~kr15s033m bipolar linear integrated circuit revision no : 1 150ma power low dropout regulator the kr15sxxxm is an efficient linear voltage regulator with very low dropout voltage(typically 10mv at light loads and 165mv at 175ma) the kr15sxxxm can be enabled, or shut down by a cmos or ttl compatible signal. when disabled. power consumption drops nearly to zero. dropout ground current is minimized to help prolong battery life. other key features include reversed battery protechion, current limiting, over temperature shutdown, and low noise performance with an ultra-low-noise option features high output voltage accuracy : 1% low quiescent current. : i q(off) =3 very low ground current : 350 (i out = 50ma) low dropout voltage : 175mv(i out =150ma) built-in on/off control terminal built -in over current , over heat protection function reverse-battery protection applications laptop, notebook, and palmtop computers cellular telephones and battery-powered equipment consumer and personal electronics pc card vcc and vpp regulation and switching smps post-regulator/dc-to-dc modules high-effciency linear power supplies 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 2 3 15 4 + _ + _ + _ + _ + _ 1. input 2. gnd 3. on/off control 4. noise bypass 5. output line-up v out (v) tsv item marking 1.8 kr15s018m a18 2.5 KR15S025M a25 2.6 kr15s026m a26 2.7 kr15s027m a27 2.8 kr15s028m a28 2.85 kr15s285m a2j 2.9 kr15s029m a29 3.0 kr15s030m a30 3.1 kr15s031m a31 3.3 kr15s033m a33 www.datasheet.in
