(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. because 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 high, noise pickup or unstable operation may result. connect a capacitor with a capacitance value as much as 4.7 f or more between v dd and gnd pin, and as close as possible to the pins. set external components, especially the output capacitor, as close as possible to the ics, and make wiring as short as possible. (refer to the typical application diagram above.) thermal shutdown ther e i s the built - in thermal - shutdown f unction i n r1 190x s eries . it discontinues operation of the ic when th e junction temperature becomes over 150 c (typ.) and ic re - operates when the junction temperature under 130 c . if the temperature increasing keeps the i c repeats on and off operating. the output becomes the pulse condition. chip enable circuit for the output voltage stability, please do not use the intermediate electric potential (the voltage value between v ceh and v cel ) that causes the supply current i ncreasing and the unstable of output voltage. delay pin is open when c d pin is not used. r1190x 8 inrush - current limit function r1190x series has the function to limit the inrush - current , it limited approximately 0.3 a when the voltage regulator is turn on. it is also possible to set time of the rush - curren t limitation by connecting capacitor with delay pin. the rush - current time (t d ) and the value of capacitor (c d (f)) is calculatable by the following formula; t d = (0.000198 + (3.79 10 7 c d )) v in the inrush - current is limited even if the capacitor is not con nected with the delay pin. in this case, the time is calculated as c d = 0 by the formula above. though, if the value of time is insufficient for controlling the inrush - current, please connect the capacitor with delay pin. the delay pin is used as open when t he capacitor is not used. please use the delay pin as open when the capacitor is not used. auto - discharge function r1190xxxxd series has the auto - discharge function. when " l " signal is put into the chip - enable pin (ce), the switch between v out and gnd is turned on and the charge at capacitor is discharge rapidly by the auto - discharge function. r1190x 9 test circuits c 1 r 1190x series v dd v out ce gnd c 2 v out delay v in i out v basic test circuit c 1 r 1190x series v dd v out ce gnd c 2 delay v in a test circuit for supply current r 1190x series v dd v out ce gnd c 2 delay i out pulse generator p. g. test circ uit for ripple rejection r1190x 10 c 1 r 1190x series v dd v out ce gnd delay v in i o u ta i outb c 2 v out test circuit for load transient response r1190x 11 typical characteristic 1 ) output voltage vs. output current (c1 = = = r1190x020x r1190x033x r1190x050x r1190x090x r1190x120x r1190x 12 2) output voltage vs. input voltage (c1 = = = r1190x020x r1190x033x r1190x050x r1190x090x r1190x120x r1190x 13 3) supply current vs. input voltage (c1 = = = r1190x020x r1190x033x r1190x050x r1190x090x r1190x120x r1190x 14 4 ) output voltage vs. temperature (c1 = = = r1190x020x r1190x033x r1190x050x r1190x090x r1190x120x r1190x 15 5) supply current vs. temperature (c1 = = r1190x020x r1190x033x r1190x050x r1190x090x r1190x120x r1190x 16 6) dropout voltage vs. output current (c1 = = r1190x020x r1190x033x r1190x050x r1190x090x r1190x120x r1190x 17 7) dropout voltage vs. set output voltage (c1 = = = 8) ripple rejection vs. input voltage ( c1 = = = = = r1190x020x r1190x033x r1190x050x r1190x090x r1190x 18 r1190x120x 9) ripple rejection vs. frequency (c1 = = = = r1190x020x r1190x033x r1190x050x r11 90x090x r1190x 19 r1190x120x 1 0 ) input transient response ( c1 = = = = = r1190x020x r1190x033x r1190x050x r1190x090x r1190x 20 r1190x120x 11) load transient response ( c1 = = = = r1190x020x r1190x033 x r1190x050x r1190x090x r1190x 21 r1190x120x 12) turn on speed with ce pin (i out = = = = = r1190x020x r1190x050x r1190x090x r1190x120x r1190x 22 13) turn off speed with ce pin (d version) ( i out = = = = = r1190x020x r1190x050x r1190x090x r1190x120x 14) inrush current at turn on ( v in = = = = = = r1190x 23 15) inrush current limit v s. c d capacitance (c1 = = r1190x050x 16) inrush current limit delay time vs. input voltage (c1 = = r1190x050x 17) thermal shutdown vs. temperature (c1 = = r1190x050x r1190x 24 esr vs. output current when using these ics, consider the following points: the relations between i out (output current) and esr of an output capacitor are shown below. the conditions when the white noise level is under 40 vrms (avg.) are marked as the hatched area in the graph. measurement conditions ?
