r1171x series 2.0a/1.5a ldo regulator no. ea-125-061107 1 outline the r1171x series are cmos-based positive voltage regulat or ics. the r1171x series have features of low dropout voltage, high output voltage accuracy, low consum ption current. each of these ics consists of a voltage reference unit, an error amplifier, resistor net for setti ng output voltage, a current limit circuit at short mode, a chip enable circuit, and thermal-shunt circuit. the output voltage of r1171 is fixed in the ic. low consumption current by the merit of cmos process and built-in transi stors with low on-resistance make low dropout voltage and chip enable function prolongs t he battery life. these regulators are remarkable improvement on the current regulators in terms of i nput transient response, and load transient response. thus, the r1171x series are suitable for various power sources. since the packages for these ics are high wattage hs op-6j package, to-252-5 (under development), high density mounting of the ics on boards is possible. features ? low supply curr ent ..................................................... typ. 130 a ? low standby curr ent ................................................... typ. 0.1 a ? output current ............................................................. min. 1.5a (v in = v out + 1.0v, r1171sxxxa/b) min. 2.0a (v in = v out + 1.0v, r1171jxxxc/d) (under development) ? input volt age ................................................................ 2.1v to 6.0v ? output voltage ............................................................. 1.5v to 5.0v (r1171sxxxa/b) 1.8v to 5.0v (r1171jxxxc/d) ? output voltage accuracy.............................................. 2.0% ? low dropout voltage .................................................... typ. 0.09v (v out = 3.0v, i out = 300ma) ? low temperature-drift coefficient of output voltage ... typ. 100ppm/ c ? line regulat ion ............................................................ typ. 0.05%/v ? packages ..................................................................... hsop-6j, to-252-5 (under development) ? built-in current limit circuit ? built-in thermal shunt circuit ? ceramic capacitor for phase compensation ................ c in = c out = ceramic 10.0 f (v out <1.8v) c in = c out = ceramic 4.7 f (v out > = 1.8v) applications ? local power source for notebook pc. ? local power source for portable appliances, cameras, and videos. ? local power source for equipment of battery-use. ? local power source for home appliances.

r1171x 20 technical notes on external components and typical application 1. phase compensation in these ics, phase compensation is made with the out put capacitor for securing stable operation even if the load current is varied. for this purpose, use a capacitor with the capacitance range from 4.7 f to 10.0 f, a s c l . in case that using a tantalum capacitor and the esr of the tantalum capacitor is too large, unstable operation may result. fully evaluation is necessary for the whole circuit with considering the frequency characteristic. 2. mounting on pcb make v dd and gnd lines sufficient. if their impedance is high, large current may flow and the pick-up noise or unstable operation may result. therefore use a capacitor with a capacitance range from 4.7 f to 10.0 f between v dd pin and gnd pin as close as possible. further, set an output capacitor between v out pin and gnd pin for phase compensation as close as possible. (refer to the example of typical application) in v dd v out ce gnd c l c i out r1171sxx1b r1171sxx1b typical application 1.5v < = v out <1.8v : c i = 10 f (ceramic),c l = 10 f (ceramic) 1.8v < = v out < = 5.0v : c i = 4.7 f (ceramic),c l = 4.7 f (ceramic) 3. output short protection function in the r1171x series, the output short protection function is built in, further, if the output is short to the gnd or other voltage line, the chip inside is heating, as a resul t, in case that the junction temperature becomes equal or more than 150 c (typ.), the built-in thermal shutdown circuit works. if the junction temperature becomes equal or more than 150 c (typ.), the ic is protected by the output shor t protection circuit and the thermal shutdown circuit.
