eup7220 ds7220 v e r1.0 jan. 2010 1 dual, low-noise, high-psrr, 150ma ldo without bypass capacitor description the eup72 2 0 is a dual-channel low noise, low dropout. high psrr, high accuracy cmos voltage regulator. performance features include low output noise, high ripple rejection ratio, low dropout and very fast turn-on times. the eup7220 is also fully compatible with low esr ceramic capacitors, reducing cost and improving output stability. this high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high psrr achieved across a broad range of frequencies. the en function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption. the eup7220 is available in small 1.6mm1.6mm tdfn-6 and tsot23-6 packages. feature s z 15 0 ma output current (per ldo) z 30v rms low no ise output z 70db psrr at 1khz z low 50ua quiescent current (both ldos active) z 2.5v to 5.5v input voltage range z 190mv dropout at 150ma load z dual shutdown pins control each output z current limiting and thermal protection z short circuit protection z available in tdfn-6 1.6mm 1.6mm and tsot23-6 packages z rohs compliant and 100% lead (pb)-free halogen-free applications z cell u lar phones z camera, video recordes z pdas z hand-held equipment typical application cir cuit figure 1. v?mw`r?y?b? w w w . g o f o t e c h . c o m
