r1160x series 3-mode 200ma ldo regulator no.ea-083-140530 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. t o 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 p acka ges for these ics are sot-23-5 and son-6 packages, high density mounting of the ics on boards is possible. features ? supply current (low po wer mode)............................... typ. 3.5 a (v out 1.5v) ? supply current (fast tr ansient mode).......................... t yp. 40 a ? supply current (standby mode).................................... typ. 0.1 a ? dropout voltage ............................................................ t y p. 0.14v (i out = 200ma, v out = 2.8v) ? ripple rejectio n............................................................ typ. 70db (f = 1khz, ft mo de) ? temperature-drift coefficient of output voltage ........... typ. 100pp m/ c ? line regulation ............................................................. t y p. 0.05%/v ? output voltage accuracy............................................... 2.0% ( 3.0% at lp mode) ? output voltage range................................................... 0.8v to 3.3v (0.1v s teps) ( for other voltages, please refer to mark informations.) ? input voltage range ..................................................... 1.4v to 6.0v ? built-in fold back protection circuit ............................. t y p. 50ma (c urrent at short mode) ? packages ..................................................................... so t- 23-5, 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: if additional ceramic capacitors are connected with parallel to the outp ut p in with an 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.) if you use a tantalum type capacitor and esr value of the capacitor is large, output might be unst a ble. evaluate your circuit with consider ing frequency characteristics. if you use a ceramic type output ca pacitor , please connect about 1 resistor in series for the stability of output voltage. dependin g on the capacitor size, manufacturer, and pa rt number , the bias char acteristics and temperature characteristics are different. evaluate the circuit with actual using capacitors. ?
