SGM2047A-3.3XXDH4G/TR

The SGM2047 is a linear regulator featuring ultra-low quiescent current, fast transient response, high accuracy, and low dropout. It delivers 200mA of output current with a typical dropout voltage of only 135mV. The input voltage range is 1.7V to 5.5V, and the output voltage range is 0.6V to 3.6V. Additional features include a logic-controlled shutdown mode, short-circuit current limiting, and thermal shutdown protection. The SGM2047A incorporates an automatic discharge function to rapidly discharge VOUT when disabled. This device is suited for applications requiring ultra-low quiescent current and fast transient response power supplies, such as low-power wireless module power supplies in wearable devices. The SGM2047 is available in Green XTDFN-1×1-4L and SOT-23-5 packages, with an operating temperature range of -40℃ to +125℃.
