rp200x series 3-mode 300ma ldo regulator no.ea-182-100208 1 outline the rp200x series consist of cmos-based voltage re gulator ics with high output voltage accuracy, low dropout voltage 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 destructi on by over current, the current limit circuit is included. the rp200x series have 3-mode. one is standby mode wi th ce pin. other two modes are realized with eco function. fast response mode (fast mode) and fast and low power auto-change mode (auto eco mode) are alternative with auto eco pin (ae pin). supply current of ic itself at light load is automatically reduced at auto eco mode compared with fast mode. the output voltage is maintained between fast mode and auto eco mode. without ae pin type is also available. it is an ldo regulator with auto eco mode. (rp200z in wlcsp.) since the packages for these ics are sot-23-5, sc-8 8a, thin dfn(plp)1212-6, and wlcsp-4-p5, high density mounting of the ics on boards is possible. rp200q (sc-88a), rp200k (dfn (plp)1212-6) and rp200n (sot-23-5) has ae pin, then if the ae pin is "h", fast mode is available. if the ae pin is set at "l" level, auto eco mode operation is available. features ? supply current (low po wer mode) .............................. typ. 1.0 a (v out 1.85v) ? supply current (fas t mode)......................................... typ. 55 a ? supply current (standby mode)................................... typ. 0.1 a ? ripple rejectio n........................................................... typ. 70db (f = 1khz) ? input voltage range .................................................... 1.4v to 5.25v ? output voltage range.................................................. 0.8v to 4.0v (0.1v steps) ( for other voltages, please refer to mark informations.) ? output voltage accuracy.............................................. 1.0% (v out > 2.0v, t opt = 25 c) ? temperature-drift coefficient of output voltage .......... typ. 50ppm/ c ? dropout voltage ........................................................... typ. 0.23v (i out = 300ma, v out = 2.8v) ? line regulation ............................................................ typ. 0.02%/v ? packages ..................................................................... dfn(plp) 1212-6, sot-23-5, sc -88a, wlcsp-4-p5 ? built-in fold back protection circuit ............................ typ. 50ma (current at short mode) ? ceramic capacitors are recommended........................ 1.0 f applications ? power source for portable communication equipment. ? power source for electrical appliances such as cameras, vcrs and camcorders. ? power source for battery-powered equipment.

rp200x 8 typical application c1 rp200x series v dd v out ce gnd v out a e c2 (external components) c1, c2 : ceramic capacitor 1.0 f murata: grm155b31a105ke15 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, use a capacitor c2 with 1.0 f or more and good esr (equivalent series resistance). (note: if additional ceramic capacitors are connected with parallel to the output pin 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.) 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 a capacitance value as much as 1.0 f or more between v dd and gnd pin, and as close as possible to the pins. set external components, especially the output capacitor c2, as close as possible to the ics, and make wiring as short as possible. impedance of input pin (ce pin and ae pin) in those ics, there is a pull-down consta nt current in the ce pin and the ae pin. however, if those pins are floating and wired long that produce the noise environmen t, it might miss-operation of ics. for this purpose, please make sure enough evaluation of ics.
