300ma ldo regulator r1130xxxxa/b/c series 1 outline the r1130xxxxx series are cmos-based voltage regulator (vr) ics. vr function has features of high ripple rejec- tion, low dropout voltage, high output voltage accuracy, and ultra-low supply current. each of these ics consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, and a current limit circuit. each of the r1130xxxxa/b type includes also a chip enable circuit. the output voltage of the r1130xxxxc type is adjustable with external resistors. the output voltage of r1130xxxxa/b is fixed in the ic. low supply current by the merit of cmos process and built-in transistors with low on-resistance make low dropout voltage. these regulators in the r1130xxxxx series are remarkable improvement on the current regulators in terms of ripple rejection, input transient response, and load transient response. maximum output current is large for its compact size. thus, the r1130xxxxx series are suitable for power supply for cd-drives, dvd-drives, and so forth. since the packages for these ics are the sot-89-5 package or hson-6p, high density mounting of the ics on boards is possible. features ? ultra-low supply current ................................................................................... typ. 50a ? low standby current ................................................................................................. typ. 0.1a (vr) for a type ? high ripple rejection ................................................................................................ typ. 60db (f=1khz) (vr) ? output current ................................................................................................................. min. 300ma (v in =v out +1v) ? output voltage (vr) .................................................................................................... stepwise setting with a step of 0.1v in the range of 1.5v to 5.0v (a/b version) (reference 1.8v (c version)) ? high output voltage accuracy ........................................................................ 2.0% (vr) for a/b type, 2.0% (reference voltage for adjustable vr) for c type ? low dropout voltage .................................................................................................. typ. 0.2v (i out =100ma) (vr) ? small package ..................................................................................................................... sot-89-5, hson-6p ? built-in current limit circuit ? low temperature-drift coefficient of output voltage .......... typ. 100ppm/ c ? absolute maximum voltage ................................................................................ 9v ? internal phase compensation (small output capacitance such as 0.1f ceramic can be used with.) applications ? power source for cd-drives and dvd-drives, hdd. ? local power source for notebook pc. no. ea-078-0305
