SGM2023 quad, low power, low dropout, 200ma, rf-linear regulators general description the SGM2023 is a quad, low-power, low-dropout, cmos linear voltage regulator that operates from 2.5v to 5.5v input and delivers up to 200ma continuous current at each channel. an ultra low ground current (350 a at 0ma output current) makes this part attractive for battery operated power systems. the SGM2023 also offers low dropout voltage (220mv at 200ma output) to prolong battery life in portable electronics. systems requiring a quiet voltage source, such as rf applications, will benefit from the SGM2023 series? ultra low output noise (30v rms ) and high psrr. an external noise bypass capacitor connected to the device?s bp pin can further reduce the noise level. other features include a 10na logic-controlled shutdown mode, output current limit and thermal shut-down protection. SGM2023 is available in green tqfn-33-16l package. it operates over an ambient temperature range of -40 to +85 . features low output noise: 30v rms typ (10hz to 100khz) low dropout voltage: 220mv at 200ma output load current low 350a no-load supply current high psrr: 70db at 1khz thermal-overload protection output current limit 10na logic controlled shutdown -40 to +85 operating temperature range available in green tqfn-33-16l package applications cellular telephones cordless telephones phs telephones pcmcia cards modems mp3 player hand-held instruments palmtop computers electronic planners portable/battery-powered equipment rev. a. 2 sg micro corp www.sg-micro.com
