utc UR233 linear integrated circuit utc unisonic technologies co., ltd. 1 qw-r102-011,c low drop fixed and adjustable positive voltage regulators description the utc UR233 is a low drop voltage regulator able to provide up to 0.8a of output current, available even in adjustable version (vref=1.25v). concerning fixed versions, are offered the following output voltages: 1.8v, 2.5v, 2.85v, 3.0v, 3.3v and 5.0v. the device is supplied in: sot-223, sot-89,to-252, to-263, to-263-3, sop-8 and to-220. the sot-223,sot-89,sop-8,to-263,to-263-3 and to-252 surface mount packages optimize the thermal characteristics even offering a relevant space saving effect. high efficiency is assured by npn pass transistor. in fact in the case, unlike than pnp one, the quiescent current flows mostly into the load. only a very common 10 f minimum capaci tor is needed for stability. on chip trimming allows the regulator to reach a very tight output voltage tolerance, within 1% at 25 c. the adjustable UR233 is pin to pin compatible with the other standard adjustable voltage regulators maintaining the better performances in terms of drop and tolerance. features *low dropout voltage (1v typ.) *output current up to 0.8a *fixed output voltage of: 1.8v,2.5v, 2,85v, 3.0v, 3.3v, 5.0v *adjustable version av ailability (vref=1.25v) *internal current and thermal limit *available in 1%(at 25 c) and 2% in all temperature range *supply voltage rejection: 75db (typ) *temperature range: 0 c to 125 c sop-8 sot-223 1 to-220 to-252 to-263 1 1 1 to-263-3 1 1 sot-89 sop-8 1: gnd; 2,3,6,7: vout; 4: vin; 5,8: nc *pb-free plating product number: UR233l www..net
