The SGM2036-1.2YUDH4G/TR is an ultra-low dropout voltage regulator (ULDO) manufactured by SGMICRO. It is a linear LDO, or low dropout voltage regulator, with an output voltage of 1.2V, a maximum quiescent current of 30uA, and a maximum dropout voltage of 300mV at full-load. The SGM2036-1.2YUDH4G/TR comes in a Package of UTDFN-4-EP (1x1) and is compliant to the RoHS directive. It is designed to offer a low noise and high power supply rejection ratio for power supply applications. It has a tight line and load regulation and includes internal protection circuits such as over temperature shutdown, overcurrent protection, and reverse current protection. The SGM2036-1.2YUDH4G/TR also provides a wide input voltage range of 2.7V to 5.5V.
