R1150H series voltage regulator(with wide input voltage range) with reset no.ea-081-0610 1 outline the R1150H series are cmos-based voltage regulator (vr) ics equipped with a voltage detector (v det ). vr function of the R1150Hxxxx has featur es of low dropout voltage, high ou tput voltage accura cy, 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 volt age are fixed in the ic, output voltage accuracy is 2.0%, while 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 regulator output voltage of this ic itself. since the package for these ics is the sot-89-5 pack age, high density mounting of the ics on boards is possible. features ? ultra-low supply cu rrent..................................................... typ. 7.0 a ? input volt age ........................................................................ max. 24.0v ? output voltage (vr) ............................................................. 2.1v to 14.0v ? detector threshold voltage (v det ) ....................................... 2.3v to 15.0v ? high output vo ltage accu racy ............................................. 2.0% (vr), 2.5% (vd) ? output current ..................................................................... min. 150ma (v out =5.0v) ? small package ..................................................................... sot-89-5 ? built-in current limit circuit, thermal shutdown circuit (vr) ? monitoring v dd voltage ......................................................... a/c type ? monitoring sense pin ( sense) voltage ................................b type ? monitoring v out pin voltag e.................................................. d type applications ? power source and reset circuit for cameras, videos and mobile telecommunication equipment. ? power source and reset circuit for battery-operated equipment. ? power source and reset circuit for home appliances. 4 .com datasheet u

R1150H 24 technical notes phase compensation phase compensation of the R1150H series has been m ade 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 0.1f or more capacitors as c in and c out . 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. 5 1 2 3 ce v out gnd R1150Hxxxa series c in v in c out i out 470k ? v dd 4 v det R1150Hxxxa typical application thermal shutdown thermal shutdown function is included in the r11 50hxxxa/b/c/d series, when the junction temperature is equal or more than +150c (typ.), the operation of regulator would stop. after that, when the junction temperature is equal or less than +120c (typ.), the oper ation 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. 4 .com datasheet u
