r1173x series super low on resistance/low voltage ldo no.ea-123-111027 1 outline the r1173x series are cmos-based positive voltage re gulator ics. the r1173x series have features of super low dropout, 1a output current capability, and -3mv typical load regulation at 1a. even the output voltage is set at 1.5v, on resistance of internal fet is typically 0.32 . therefore, applications that require a large current at small dropout are suitable for the r1173x series. low input voltage is acceptable and low output voltage can be set. the minimum input voltage is 1.4v, and the lowest se t output voltage is 0.8v. each of these ics consists of a voltage reference unit, an error amplifier, resistor net for setting output voltage, a current limit circuit at over-current, a chip enable circuit, a thermal-shutdo wn circuit, and so on. a stand-by mode with ultra low consumption current can be realized with the chip enabl e pin. the output voltage types of r1173 are fixed one in the ic and adjustable one (r1173x001x). since the packages for these ics are the sot-89-5 package, hson-6, or hsop-6j, high density mounting of the ics on boards is possible. features ? output current ............................................................. 1a ? supply curre nt ............................................................. typ. 60 a ? standby current ........................................................... typ. 0.1 a ? input voltage range .................................................... 1.4v to 6.0v ? output voltage rang e.................................................. 0.8v to 5.0v (0 .1v steps) (r1173xxx1) 1.0v to v in (r1173x001) ( for other voltages, please refer to mark informations.) ? dropout voltage ........................................................... typ. 0.32v (v out = 1.5v, i out = 1a) typ. 0.18v (v out = 2.8v, i out = 1a) ? ripple rejectio n........................................................... typ. 70db (v out = 2.8v) ? output voltage accuracy.............................................. 2.0% ? temperature-drift coefficient of output voltage........... typ. 100ppm/ c ? line regulation ............................................................ typ. 0.05%/v ? load regulati on........................................................... typ. ? 2mv (i out = 300ma) typ. ? 3mv (i out = 1a) ? packages ..................................................................... sot-89-5 , hson-6, hsop-6j ? low inrush current at turning-on .................................. typ. 500ma ? built-in thermal shutdown circuit ? built-in current limi t circuit ......................................... typ. 250ma ? output ca pacitors ......................................................... c in = ceramic 4.7 f c out = tantalum 4.7 f (v out <1.0v) c out = ceramic 4.7 f (v out > = 1.0v) applications ? local power source for notebook pc. ? local power source for portable communication equipments, cameras, and videos. ? local power source for home appliances.
