mc78lc00 series http://onsemi.com 8 applications information a typical application circuit for the mc78lc00 series is shown in figure 20. input decoupling (c1) a 0.1 f capacitor either ceramic or tantalum is recommended and should be connected close to the mc78lc00 package. higher values and lower esr will improve the overall line transient response. output decoupling (c2) the mc78lc00 is a stable component and does not require any specific equivalent series resistance (esr) or a minimum output current. capacitors exhibiting esrs ranging from a few m up to 3.0 can thus safely be used. the minimum decoupling value is 0.1 f and can be augmented to fulfill stringent load transient requirements. the regulator accepts ceramic chip capacitors as well as tantalum devices. larger values improve noise rejection and load regulation transient response. hints please be sure the vin and gnd lines are sufficiently wide. when the impedance of these lines is high, there is a chance to pick up noise or cause the regulator to malfunction. set external components, especially the output capacitor, as close as possible to the circuit, and make leads as short as possible. thermal as power across the mc78lc00 increases, it might become necessary to provide some thermal relief. the maximum power dissipation supported by the device is dependent upon board design and layout. mounting pad configuration on the pcb, the board material, and also the ambient temperature effect the rate of temperature rise for the part. this is stating that when the mc78lc00 has good thermal conductivity through the pcb, the junction temperature will be relatively low with high power dissipation applications. the maximum dissipation the package can handle is given by: pd t j(max) t a r ja if junction temperature is not allowed above the maximum 125 c, then the mc78lc00ntr can dissipate up to 357 mw @ 25 c. the power dissipated by the mc78lc00ntr can be calculated from the following equation: p tot v in *i gnd (i out ) [ v in v out ] *i out or v inmax p tot v out * i out i gnd i out if an 80 ma output current is needed then the ground current from the data sheet is 1.1 a. for an mc78lc30ntr (3.0 v), the maximum input voltage will then be 7.4 v. v out c2 + c1 + battery or unregulated voltage figure 20. basic application circuit for ntr suffixes
