6 / 8 page 204 Regulator ICs BA3950A FApplication example FOperation notes (1) Operating power supply voltage When operating within proper ranges of power supply voltage and ambient temperature, most circuit functions are guaranteed. Although the rated values of electrical characteristics cannot be absolutely guaranteed, char- acteristic values do not change drastically within the proper ranges. (2) Power dissipation (Pd) Refer to the heat reduction characteristics (Fig. 4) and the rough estimation of IC power dissipation given on a separate page. If power dissipation exceeds the allow- able limit, the functionality of IC will be degraded (such as reduction of current capacity by increased chip tem- perature). Make sure to use the IC within the allowable range of power dissipation with a sufficient margin. (3) Preventing oscillation at each output To stop oscillation of output, make sure to connect a ca- pacitor having a valve 1 µF or greater between GND and each output pin. Also, be sure to connect a bypass ca- pacitor between VCC and GND for further stabilization of output. (To avoid the noise effect, layout the grounding close to the IC.) Oscillation can occur if capacitance is susceptible to temperature. We recommend using a tan- talum electrolytic capacitor with minimal changes in ca- pacitance. |
