r1160x series 3-mode 200ma ldo regulator no.ea-083-0607 1 outline the r1160x series consist of cmos-based voltage r egulator ics with high output voltage accuracy, low supply current, and low on-resistance. each of these vo ltage regulator ics consists of a voltage reference unit, an error amplifier, resistors for setting output volt age, a current limit circuit, and a chip enable circuit. these ics perform with low dropout voltage and a chip enable function. to prevent the destruction by over current, current limit circuit is included. the r1160x series have 3-mode. one is standby mode with ce or standby control pin. other two modes are realized wi th eco pin?. fast transient mode (ft mode) and low power mode (lp mode) are alternative with eco pin?. c onsumption current is reduced to 1/10 at low power mode compared with fast transient mode. output voltage is maintained between ft mode and lp mode. the output voltage of these ics is internally fixed with high accuracy. since the packages for these ics are sot-23-5 and son-6 packages, high density mounting of the ics on boards is possible. features ? ultra-low supply cu rrent..................................typ. 3.5 a (low power mode, v out < = 1.5v) typ. 40 a (fast transient mode) ? standby mode ...................................................typ. 0.1 a ? low dropout voltage .........................................typ. 0.30v (i out = 200ma 3.0v output voltage=1.0v type) typ. 0.20v (i out = 200ma 3.0v output voltage=1.5v type) typ. 0.14v (i out = 200ma 3.0v output voltage=3.0v type) ? high ripple rejectio n .......................................typ. 70db (f =1khz,ft mode) ? 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% ( 3.0% at lp mode) ? output voltage ..................................................0.8v to 3.3v ? input voltage .....................................................min.1.4v ? built-in fold back protecti on circuit .................typ. 50ma (current at short mode) ? small packages ..............................................sot-23-5 (super mini-mold),son-6 applications ? precision voltage references. ? power source for electrical appliances such as cameras, vcrs and hand-held communication equipment. ? power source for battery-powered equipment.

(note: when the additional ceramic capacitors are connect ed to the output pin with output capacitor for phase compensation, the operation might be unstable. because of this, test these ics with as same external components as ones to be used on the pcb.) if you use a tantalum type capacitor and esr value of the capacitor is large, output might be unstable. evaluate your circuit with consider ing frequency characteristics. depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature characteristics are different. evaluate the circuit with actual using capacitors.
r1160x 28 esr vs. output current when using these ics, consider the following points: in these ics, phase compensation is made for securing stable operation even if the output current is varied. for this purpose, be sure to use a capacitor c out with good frequency characteristics and esr (equivalent series resistance) in the range described as follows: the relations between i out (output current) and esr of output ca pacitor are shown below. the conditions when the white noise level is under 40v (avg.) are marked as the hatched area in the graph.
