mc78pc00 series http://onsemi.com 12 application hints when using these circuits, please be sure to observe the following points: ? phase compensation is made for securing stable operation even if the load current varies. for this reason, be sure to use a capacitor c out with good frequency characteristics and esr (equivalent series resistance) as described in the graphs on page 11. on page 11, the relations between i out (output current) and esr of output capacitor are shown. the conditions where the white noise level is under 40 v (avg.) are marked by the shaded area in the graph. (note: when additional ceramic capacitors are connected to the output pin with output capacitor for phase compensation, there is a possibility that the operation will be unstable. because of this, test these circuits with as same external components as ones to be used on the pcb). 1 v in 5 v out 3 2 gnd ce ceramic capacitor 1.0 f figure 46. measuring circuit for white noise: mc78pc30 ceramic capacitor s.a. spectrum analyser esr i out 4.0 v measuring conditions: (1) frequency range: 10 hz to 1.0 mhz measuring conditions: (2) temperature: 25 c ? please be sure the v in and gnd lines are sufficiently wide. when the impedance of these lines is high, there is a chance to pick up noise or to malfunction. ? connect the capacitor with a capacitance of 1.0 f or more between v in and gnd as close as possible to v in or gnd. ? set external components, especially the output capacitor, as close as possible to the circuit, and make the wiring as short as possible. v in v out gnd cap. mc78pcxx ce cap. in figure 47. typical application out ++
