ncp583 http://onsemi.com 674 application information input decoupling a 1.0 f ceramic capacitor is the recommended value to be connected between v in and gnd. for pcb layout considerations, the traces of v in and gnd should be sufficiently wide in order to minimize noise and prevent unstable operation. output decoupling it is recommended to use a 0.1 f ceramic capacitor on the v out pin. for better performance, select a capacitor with low equivalent series resistance (esr). for pcb layout considerations, place the output capacitor close to the output pin and keep the leads short as possible. ordering information device output t ype / features nominal output v oltage marking package shipping ncp583sq15t1g active high w/enable 1.5 a5 sc ? 82ab (pb ? free) 3000 tape & reel ncp583sq18t1g active high w/enable 1.8 a8 sc ? 82ab (pb ? free) 3000 tape & reel ncp583sq25t1g active high w/enable 2.5 b5 sc ? 82ab (pb ? free) 3000 tape & reel ncp583sq28t1g active high w/enable 2.8 b8 sc ? 82ab (pb ? free) 3000 tape & reel ncp583sq30t1g active high w/enable 3.0 c0 sc ? 82ab (pb ? free) 3000 tape & reel ncp583sq33t1g active high w/enable 3.3 c3 sc ? 82ab (pb ? free) 3000 tape & reel ncp583xv15t1g* active high w/enable 1.5 g15b sot ? 563 (pb ? free) 4000 tape & reel ncp583xv18t1g* active high w/enable 1.8 g18b sot ? 563 (pb ? free) 4000 tape & reel NCP583XV25T1G* active high w/enable 2.5 g25b sot ? 563 (pb ? free) 4000 tape & reel ncp583xv28t1g* active high w/enable 2.8 g28b sot ? 563 (pb ? free) 4000 tape & reel ncp583xv29t1g* active high w/enable 2.9 g29b sot ? 563 (pb ? free) 4000 tape & reel ncp583xv30t1g* active high w/enable 3.0 g30b sot ? 563 (pb ? free) 4000 tape & reel ncp583xv33t1g* active high w/enable 3.3 g33b sot ? 563 (pb ? free) 4000 tape & reel *samples and production start 1q05.
