2002.jul.29 rev. 1.11 - 1 - voltage regu l ator (with wide input voltage range) with reset r1 15 0 h xxx x series n outlin e the R1150HXXXX series are cmos-based voltage regulator (vr) ics equipped with a voltage detector (v det ). vr function of the R1150HXXXX has features of low dropout voltage , high output voltage accuracy, and ultra-low supply current. each of the r1150hxxxa types includes also a chip enable circuit. the output of built-in voltage detector is nch open drain type. the r1150hxxxc/d types have a pin for connecting external capacitor to set a certain reset delay time instead of chip enable control pin. the regulator output voltage and the detector threshold voltage are fixed in the ic. the output voltage accuracy is 2.0%, while the detector threshold accuracy is 2.5%. the r1150hxxxa (with chip enable function) and c series can supervise input voltage by the built-in detector. r1150hxxxb type can supervise sense pin voltage by the built-in detector. r1150hxxxd type can supervise v out voltage, or the regulator output voltage of this ic itself. since the package for these ics is the sot-89-5 package, high density mounting of the ics on boards is possible. n features l ultra-low supply current t yp . 7 a l in put voltage max . 24 v l output voltage (vr) stepwise setting with a step of 0.1v in the range of 2.1v to 14.0v l detector threshold voltage (v det ) stepwise setting with a step of 0.1v in the range of 2.3v to 15.0v l high output voltage accuracy 2.0% (vr) 2. 5 % (vd) l output current min . 150ma ( v out = 5v ) l small package sot-89-5 l built-in current limit circuit , thermal shutdown circuit (vr) l monitoring v dd voltage a/c type m onitoring sense pin ( sense ) voltage b type monitoring v out pin voltage d type n a pplication s l power source and reset circuit for cameras, videos and mobile telecommunication equipment. l power source and reset circuit for battery-operated equipment. l power source and reset circuit for home appliances.

rev. 1.11 - 23 - n technical notes phase compensation phase compensation of the r1150h series has been made internally for stable operation even though the load current would vary. therefore, without the capacitors, c in and c out , output voltage is regulated, but for more stable operation, use capacitors as c in and c out . recommended value is in the range from 0. 1 f to 1 .0 f. wiring should be made as short as possible. pcb layout current flows into wiring for v dd or gnd, thus, if the impedance of the wiring is rather high, it may cause of making noise or unstable operation, thus width and pattern should be enough wide to avoid such problems. connect the capacitor, c in between v dd pin and gnd pin as close as possible. r1150hxxxa typical application thermal shutdown thermal shutdown function is included in the r1150hxxxa/b/c/d series, when the junction temperature is equal or more than +150 c (typ.), the operation of regulator would stop. after that, when the junction temperature is equal or less than +120 c (typ.), the operation of regulator would restart. unless the cause of rising temperature would remove, the regulator repeats on and off, and output waveform would be like consecutive pulses. chip enable circuit do not make voltage level of chip enable pin keep floating level, or in between v ih and v il. unless otherwise, output voltage would be unstable or indefinite, or unexpected current would flow internally. output delay time for release v det in the r1150hxx1c/d can set an output delay time for release voltage detector with connecting a capacitor to c d pin. when an input voltage (in the case of r1150hxx1c) or an output voltage (in the case of r1150hxx1d) surpasses the release voltage of its voltage detector (+v det ), the capacitor which is connected to c d pin is started to be charged, as a result, c d pin voltage rises. when the c d pin voltage surpasses c d pin threshold voltage, the output voltage of the voltage detector outputs ? h ? . 470k w gnd v dd ce v out v in c in r1150h xxxa series v det 5 3 4 1 2 i out
