ncp698 http://onsemi.com 7 applications information a typical application circuit for the ncp698 is shown in figure 1. input decoupling (c1) a 1.0 f capacitor either ceramic or tantalum is recommended and should be connected close to the ncp698 package. higher values and lower esr will improve the overall line transient response. tdk capacitor: c2012x5r1c105k, or c1608x5r1a105k output decoupling (c2) the ncp698 is a very stable regulator 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 10 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 im prove noise rejection and load regulation transient response. tdk capacitor: c2012x5r1c105k, c1608x5r1a105k, or c3216x7r1c105k enable operation the enable pin will turn on the regulator when pulled high and turn off the regulator when pulled low. these limits of threshold are covered in the electrical specification section of this data sheet. if the enable is not used, then the pin should be connected to v in . 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. place 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 ncp698 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 devices have 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 ncp698 can dissipate up to 250 mw @ 25 c. the power dissipated by the ncp698 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 2.5 a. for an ncp698 (3.0 v), the maximum input voltage will then be 6.0 v. figure 12. r ja vs. pad copper area (1 oz cu thickness) ja (c/w) 700 500 400 200 100 pcb copper area (mm 2 ) 150 350 190 0 600 170 250 210 230 no pin connected to cu plane 300 270 290 310 330 pin 2 connected to cu plane
