The SGM2203-3.3YK3G/TR is a Low Dropout Regulator (LDO) manufactured by SGMICRO. It is a three-terminal positive fixed voltage regulator in a SOT-89-3 (small outline transistor) package, compliant with the European Union Restriction of Hazardous Substances (RoHS) directives. It has a maximum input voltage of 20V and a maximum output current of 1A. It offers an extremely low quiescent current (operating current) of as low as 80uA and an outstanding line and load regulation with a high ripple rejection as low as 70dB at 150kHz. The SGM2203-3.3YK3G/TR is specifically designed to satisfy the requirements of low-power portable applications. These include mobile phones, PDAs, digital still cameras, and other applications that require a low-noise, low-power, small form factor voltage regulator.
