SG2003/a sg2004/a general description the SG2003/a and sg2004/a low-power, low-noise, low-dropout, cmos linear voltage regulators operate from a 2.5v to 5.5v input and deliver up to 400ma (400ma peak SG2003 only). they are the perfect choice for low voltage, low power applications. an ultra low ground current (120 a at 400ma output) make them attractive for battery operated power systems. the SG2003/a and sg2004/a series also offer ultra low dropout voltage (280mv at 400ma output) to prolong battery life in portable electronics. systems requiring a quiet voltage source, such as rf applications, will benefit from the SG2003/a and sg2004/a series? ultra low output noise (30vrms). an external noise bypass capacitor connected to the device?s bp pin can further reduce the noise level. the output voltage is preset to voltages in the range of 1.5v to 4.5v. other features include a 10na logic-controlled shutdown mode, foldback current limit and thermal shut-down protection. SG2003/a comes in 5-pin sot23 package and sg2004/a comes in 8-pin so package. applications cellular telephones cordless telephones phs telephones pcmcia cards modems mp3 players hand-held instruments palmtop computers electronic planners portable/battery-powered equipment 400ma, low power, low noise, low dropout, linear regulators features - low output noise: 30v rms typ(10hz to 100khz) - ultra-low dropout voltage: 280mv at 400ma output - low 77a no-load supply current - low 120a operating supply current at 400ma output - thermal-overload protection - output current limit - preset output voltages (1.6 % accuracy) - 10na logic-controlled shutdown - available in multiple output voltage versions fixed outputs of 2.5v, 2.8v, 2.85v, 3.0v, and 3.3v adjustable output from 1.5v to 4.5v pin configurations top view 1 2 3 4 5 6 7 8 so-8 sg2004/a en in out bp/fb gnd gnd gnd gnd 1 2 3 4 5 out in sot23-5 gnd en bp/fb SG2003/a shengbang microelectronics co, ltd tel: 86/451/84348461 www.sg-micro.com rev. b
