r1140q series 120ma ldo regulator no.ea-074-0606 1 outline the r1140q series are cmos-based voltage regulator ics with high output voltage accuracy, low supply current, low on-resistance, and high ripple rejection. each of these voltage regulator ics consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a current limit circuit, and a chip enable circuit. these ics perform with low dropout voltage and a chip enable function. the line transient response and load transient response of the r1140q series are excellent, t hus these ics are very suitable for the power supply for hand-held communication equipment. the output voltage of these ics is internally fixed with high accuracy. since the package for these ics is sc-82ab (super mini-mold) package, high density mounting of the ics on boards is possible. features ? ultra-low supply cu rrent............................................. typ. 75 a ? standby mode .............................................................. typ. 0.1 a ? low dropout voltage .................................................... typ. 0.15v (i out = 100ma, output voltage=3.0v type) ? high ripple reje ction .................................................. typ. 75db (f=1khz) ? low temperature-drift coefficient of output voltage... typ. 100ppm/ c ? excellent line regula tion ............................................ typ. 0.05%/v ? high output vo ltage accu racy ..................................... 2.0% ? output voltage rang e.................................................. 1.5v to 4.0v ? excellent dynamic response ? small package ............................................................. sc-82ab (super mini-mold) ? built-in chip enable circuit (b/d : active high) ? built-in fold-back protecti on circuit............................ typ. 40ma (current at short mode) application ? power source for cellular phones such as gsm, cdma and various kinds of pcs. ? power source for electrical appliances such as cameras, vcrs and camcorders. ? power source for battery-powered equipment.

r1140q 5 technical notes when using these ics, consider the following points: phase compensation in these ics, phase compensation is made for securing st able operation even if the load current is varied. for this purpose, be sure to use a 2.2f or more capacitor c out with good frequency characteristics and esr (equivalent series resistance). (note: when the additional ceramic capacitors are connected to the output pin with output capacitor for phase compensation, the operation might be unstable. becaus e of this, test these ics with as same external components as ones to be used on the pcb.) pcb layout make v dd and gnd line sufficient. when the impedance of these is high, it would be a cause of picking up the noise or unstable operation. connect a capacitor with as much as 1.0f capacitor between v dd and gnd pin as close as possible. set external components, especially output capacitor as close as possible to the ics and make wiring shortest. typical application v out 1 4 2 3 v dd gnd ce c2 c1 in out r1140q series (external components) output capacitor; tantalum type
