1 ? fn6620.0 ISL9000AMRNCEP dual ldo with low noise, very high psrr and low i q isl9000amrncp is a high performance dual ldo capable of sourcing 100ma current from each output. it has a low standby current and very high psrr and is stable with output capacitance of 1f to 10f with esr of up to 200m . the device integrates an individual power-on-reset (por) function for each output. the por delay for vo2 can be externally programmed by connecting a timing capacitor to the cpor pin. the por delay for vo1 is internally fixed at approximately 2ms. a reference bypass pin is also provided for connecting a noise filtering capacitor for low noise and high-psrr applications. the quiescent current is typically only 42a with both ldo?s enabled and active. separate enable pins control each individual ldo output. when both enable pins are low, the device is in shutdown, typically drawing less than 0.1a. output voltage for the ldo are vout1 = 3.3v and vout2 = 1.8v. device information the specifications for an enhanced product (ep) device are defined in a vendor item drawing (vid), which is controlled by the defense supply center in columbus (dscc). ?hot-links? to the applicable vid and other supporting application information are provided on our website. pinout isl9000amncep (10 ld 3x3 dfn) top view features ? integrates two 100ma high performance ldo?s ?i out per channel is 50ma at t j = +150c ? excellent transient response to large current steps ? 1.8% accuracy over all operating conditions ? excellent load regulation: < 0.1% voltage change across full range of load current ? low output noise: typically 30v rms @ 100a (1.5v) ? very high psrr: 90db @ 1khz ? extremely low quiescent current: 42a (both ldos active) ? wide input voltage capability: 2.3v to 5.5v ? low dropout voltage: typically 200mv @ 100ma ? stable with 1f to 10f ceramic capacitors ? separate enable and por pins for each ldo ? soft-start and staged turn-on to limit input current surge during enable ? current limit and overheat protection ? tiny 10 ld 3x3mm dfn package ? -55c to +125c operating temperature range applications ? pdas, cell phones and smart phones ? portable instruments, mp3 players ? handheld devices including medical handheld vin en1 en2 cbyp cpor vo1 vo2 por2 por1 gnd 2 3 4 1 5 9 8 7 10 6 ordering information vendor part number (notes 1, 2) vendor item drawing part marking vo1 voltage (v) vo2 voltage (v) temp range (c) package pkg dwg. # ISL9000AMRNCEP v62/08609-01xb dkta 3.3 1.8 -55 to +125 10 ld 3x3 dfn l10.3x3c notes: 1. add -t to part number for tape and reel. 2. devices must be procured to the vendor part number. data sheet caution: these devices are sensitive to electrosta tic discharge; follow proper ic handling procedures. 1-888-intersil or 1-888-468-3774 | intersil (and design) is a registered trademark of intersil americas inc. copyright ? intersil americas inc. 2007. all rights reserved. all other trademarks mentioned are the property of their respective owners. december 12, 2007
