  r1163x series 3-mode 150ma ldo regulator with the reverse current protection no.ea-118-100317 1 outline the r1163x series consist of cmos-based voltage regul ator ics with high output voltage accuracy and low supply current. these ics perform with the chip enable function and realize a standby mode with ultra low supply current. to prevent the destruction by over current, the current limit circuit is included. the r1163x series have 3-mode. one is standby mode with ce or standby control pin. other two modes are realized with eco pin. fast transient mode (ft mode) and low power mode (lp mode) ar e alternative with eco pi n. consumption current is reduced at low power mode compared with fast tr ansient mode. the output voltage is maintained between ft mode and lp mode. further, the reverse current protection circuit is built-in. therefore, if a higher voltage than v dd pin is forced to the output pin, the reverse current to v dd pin is very small (max. 0.1 a) , so it is suitable for backup circuit. since the packages for these ics are sot-23-5, son-6, and dfn(plp)1616-6 packages, high density mounting of the ics on boards is possible. features ? supply current ..................................................... typ. 6.0 a (low power mode), typ. 70 a (fast transient mode) ? standby mode ...................................................... typ. 0.6 a ? reverse curr ent................................................... max. 0.1 a ? input voltage range ............................................ 2.0v to 6.0v ? output voltage range.......................................... 1.5v to 5.0v (0.1v steps) ( for other voltages, please refer to mark informations.) ? output voltage accuracy...................................... 1.5% ( 2.5% at low power mode) ? temperature-drift coefficient of output voltage .. typ. 100ppm/ c ? dropout voltage ................................................... typ. 0.25v (i out = 150ma, v out = 2.8v) ? ripple rejectio n................................................... typ. 70db (f = 1khz, fast transient mode) ? line regulatio n .................................................... typ. 0.02%/v (f ast transient mode) ? packages ............................................................ dfn( plp)1616-6, sot-23-5, son-6 ? built-in fold-back protection circuit ....................... typ. 40ma (current at short mode) ? performs with ceramic capacitors ...................... c in = ceramic 1.0 f, c out = ceramic 0.47 f applications ? precision voltage references. ? power source for electrical appliances such as cameras, vcrs and hand-held communication equipment. ? power source for battery-powered equipment.

(test these ics with as same external components as ones to be used on the pcb.) when a tantalum capacitor is used with this ic, if the equi valent series resistor (esr) of the capacitor is large, output voltage may be unstable. pcb layout make v dd and gnd lines sufficient. if their impedance is hi gh, noise pickup or unstable operation may result. connect a capacitor c1 with as much as 1.0 f capacitor between v dd and gnd pin as close as possible. set external components such as an output capacitor c2 , as close as possible to the ics and make wiring as short as possible.

r1163x 29 technical notes when using these ics, consider the following points: 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 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.
