ncp5663, ncv5663 http://onsemi.com 9 application information the ncp5663/ncv5663 is a high performance low dropout 3.0 a linear regulator suitable for high power applications, featuring an ultra ? fast response time and low noise without a bypass capacitor. it is offered in both fixed and adjustable output versions with voltages as low as 0.9 v. additional features, such as enable and error flag (fixed output version) increase the utility of the ncp5663/ncv5663. it is thermally robust and includes the safety features necessary during a fault condition, which provide for an attractive high current ldo solution for server, asic power supplies, networking equipment applications, and many others. input capacitor the recommended input capacitor value is a 150 f oscon with an equivalent series resistance (esr) of 50 m . it is especially required if the power source is located more than a few inches from the ncp5663/ncv5663. this capacitor will reduce device sensitivity and enhance the output transient response time. the pcb layout is very important and in order to obtain the optimal solution, the vin and gnd traces should be sufficiently wide to minimize noise and unstable operation. output capacitor proper output capacitor selection is required to maintain stability. the ncp5663/ncv5663 is stable for c out as low as 10 f (figures 15 and 16) and guaranteed to be stable at an output capacitance of, c out > 33 f with an esr between 50 m and 300 m over the output current range of 10 ma to 3.0 a. for pcb layout considerations, place the recommended ceramic capacitor close to the output pin and keep the leads short. this should help ensure ultra ? fast transient response times. adjustable output operation the application circuit for the adjustable output version is shown in figure 1. the reference voltage is 0.9 v and the adjustable pin current is typically 40 na. a resistor divider network, r1 and r2, is calculated using the following formula: r1 r2 v out v ref 1 c in c out input output ncp5663 enable on off v in v out en adj v out = 0.9 v gnd figure 17. to achieve the minimum output voltage, adj to v out has to be connected together current limit operation as the peak output current increases beyond its limitation, the device is internally clampled to 4.5 a, thus causing the output voltage to decrease and go out of regulation. this allows the device never to exceed the maximum power dissipation. error flag operation the error flag pin on the ncp5663/ncv5663 will produce a logic low when it drops below the nominal output voltage. refer to the electrical characteristics for the threshold values at which point the error flag goes low. when the ncp5663/ncv5663 is above the nominal output voltage, the error flag will remain at logic high. the external pullup resistor needs to be connected between v in and the error flag pin. a resistor of approximately 100 k is recommended to minimize the current consumption. no pullup resistor is required if the error flag output is not being used. thermal consideration this series contains an internal thermal limiting circuit that is designed to protect the regulator in the event that the maximum junction temperature is exceeded. this feature provides protection from a catastrophic device failure due to accidental overheating. it is not intended to be used as a substitute for proper heat sinking. the maximum device power dissipation can be calculated by: p d t j(max) t a r ja the bipolar process employed for this ic is fully characterized and rated for reliable 18 v v ccmax operation. to avoid damaging the part or degrading it?s reliability, power dissipation transients should be limited to under 30 w for d 2 pak. for open ? circuit to short ? circuit transient, p dtransient = v ccmax * i sc .
