ncp699 http://onsemi.com 6 definitions load regulation the change in output voltage for a change in output current at a constant temperature. dropout voltage the input/output differential at which the regulator output no longer maintains regulation against further reductions in input voltage. measured when the output drops 3.0% below its nominal. the junction temperature, load current, and minimum input supply requirements affect the dropout level. maximum power dissipation the maximum total dissipation for which the regulator will operate within its specifications. quiescent and ground current the quiescent current is the current which flows through the ground when the ldo operates without a load on its output: internal ic operation, bias, etc. when the ldo becomes loaded, this term is called the ground current. it is actually the difference between the input current (measured through the ldo input pin) and the output current. line regulation the change in output voltage for a change in input voltage. the measurement is made under conditions of low dissipation or by using pulse technique such that the average chip temperature is not significantly affected. line transient response typical over and undershoot response when input voltage is excited with a given slope. thermal protection internal thermal shutdown circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. when activated at typically 160 c, the regulator turns off. this feature is provided to prevent failures from accidental overheating. maximum package power dissipation the maximum power package dissipation is the power dissipation level at which the junction temperature reaches its maximum operating value, i.e. 125 c. depending on the ambient power dissipation and thus the maximum available output current.
ncp699 http://onsemi.com 7 applications information a typical application circuit for the ncp699 series is shown in figure 1, front page. input decoupling (c in ) a 1.0 f capacitor either ceramic or tantalum is recommended and should be connected close to the ncp699 package. higher values and lower esr will improve the overall line transient response. tdk capacitor: c2012x5r1c105k, or c1608x5r1a105k output decoupling (c out ) the ncp699 is a 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 5.0 can thus safely be used. the minimum decoupling value is 1.0 f and can be augmented to fulfill stringent load transient requirements. the regulator accepts ceramic chip capacitors as well as tantalum capacitors. larger values improve 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 suf ficiently 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 ncp699 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 ncp699 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 ncp699 can dissipate up to 400 mw @ 25 c. the power dissipated by the ncp699 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 ) i out if an 150 ma output current is needed then the ground current from the data sheet is 40 a. for an ncp699 (3.0 v), the maximum input voltage will then be 5.65 v. ordering information device nominal output voltage* marking package shipping ? ncp699sn13t1g 1.3 ljy tsop ? 5 (pb ? free) 3000 units/ 7 tape & reel ncp699sn14t1g 1.4 aa4 ncp699sn15t1g 1.5 ljp ncp699sn18t1g 1.8 ljs ncp699sn25t1g 2.5 ljt ncp699sn28t1g 2.8 lju ncp699sn29t1g 2.9 acp ncp699sn30t1g 3.0 ljv ncp699sn31t1g 3.1 aae ncp699sn33t1g 3.3 ljw NCP699SN34T1G 3.4 acf ncp699sn45t1g 4.5 acq ncp699sn50t1g 5.0 ljx *additional voltages in 100 mv steps are available upon request by contacting your on semiconductor representative. ?for information on tape and reel specifications, including part orientation and tape sizes, please refer to our tape and reel packaging specification brochure, brd8011/d.
