ncp582 http://onsemi.com 10 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 best to use a 1.0 f capacitor value when v out 2.5 v and a 0.47 f when v out 2.5 v. 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 as short as possible. noise decoupling the ncp582 series are low noise regulators and reach a noise level of only 30 vrms between 10 hz and 100 khz. ordering information device output t ype / features nominal output voltage marking package shipping ? ncp582dsq15t1g active high w/auto discharge 1.5 sf sc ? 82ab (pb ? free) 3000 tape & reel NCP582DSQ18T1G active high w/auto discharge 1.8 sj sc ? 82ab (pb ? free) 3000 tape & reel ncp582dsq25t1g active high w/auto discharge 2.5 tf sc ? 82ab (pb ? free) 3000 tape & reel ncp582dsq28t1g active high w/auto discharge 2.8 tj sc ? 82ab (pb ? free) 3000 tape & reel ncp582dsq30t1g active high w/auto discharge 3.0 ua sc ? 82ab (pb ? free) 3000 tape & reel ncp582dsq33t1g active high w/auto discharge 3.3 ud sc ? 82ab (pb ? free) 3000 tape & reel ncp582lsq15t1g active low 1.5 jf sc ? 82ab (pb ? free) 3000 tape & reel ncp582lsq18t1g active low 1.8 jj sc ? 82ab (pb ? free) 3000 tape & reel ncp582lsq25t1g active low 2.5 kf sc ? 82ab (pb ? free) 3000 tape & reel ncp582lsq28t1g active low 2.8 kj sc ? 82ab (pb ? free) 3000 tape & reel ncp582lsq30t1g active low 3.0 la sc ? 82ab (pb ? free) 3000 tape & reel ncp582lsq33t1g active low 3.3 ld sc ? 82ab (pb ? free) 3000 tape & reel ncp582dxv15t2g active high w/auto discharge 1.5 f15d sot ? 563 (pb ? free) 4000 tape & reel ncp582dxv18t2g active high w/auto discharge 1.8 f18d sot ? 563 (pb ? free) 4000 tape & reel ncp582dxv25t2g active high w/auto discharge 2.5 f25d sot ? 563 (pb ? free) 4000 tape & reel ncp582dxv28t2g active high w/auto discharge 2.8 f28d sot ? 563 (pb ? free) 4000 tape & reel ncp582dxv29t2g active high w/auto discharge 2.9 f29d sot ? 563 (pb ? free) 4000 tape & reel ncp582dxv30t2g active high w/auto discharge 3.0 f30d sot ? 563 (pb ? free) 4000 tape & reel ncp582dxv33t2g active high w/auto discharge 3.3 f33d sot ? 563 (pb ? free) 4000 tape & reel ncp582lxv15t2g active low 1.5 f15a sot ? 563 (pb ? free) 4000 tape & reel ncp582lxv18t2g active low 1.8 f18a sot ? 563 (pb ? free) 4000 tape & reel ncp582lxv25t2g active low 2.5 f25a sot ? 563 (pb ? free) 4000 tape & reel ncp582lxv28t2g active low 2.8 f28a sot ? 563 (pb ? free) 4000 tape & reel ncp582lxv29t2g active low 2.9 f29a sot ? 563 (pb ? free) 4000 tape & reel ncp582lxv30t2g active low 3.0 f30a sot ? 563 (pb ? free) 4000 tape & reel ncp582lxv33t2g active low 3.3 f33a sot ? 563 (pb ? free) 4000 tape & reel ?for information on tape and reel specifications, including part orientation and tape sizes, please refer to our tape and reel packaging specification brochure, brd801 1/d. other voltages are available. consult your on semiconductor representative.
