SGM2033-1.8XN5G/TR

The SGM2033-1.8XN5G/TR is a linear low-dropout (LDO) voltage regulator manufactured by SG Micro Corp. It is designed for applications requiring ultra-low noise and high power supply rejection ratio (PSRR), making it suitable for sensitive analog and RF circuits.

This regulator offers a wide input voltage range of 1.8V to 5.5V and a fixed or adjustable output voltage range from 1.2V to 5.0V. It can deliver up to 250mA of output current with a typical low dropout voltage of 175mV at 250mA for the SOT-23-5 package. Key electrical features include an ultra-low quiescent current of 13.5μA and a shutdown current of 0.1μA.

Additional protective features include output short-circuit protection and thermal shutdown protection. The SGM2033 series is available in SOT-23-5 and UTDFN-1x1-4AL packages and operates across a temperature range of -40℃ to +125℃. It is designed to be stable with small ceramic capacitors, simplifying external component selection.

Applications for this LDO include portable electronic devices, battery-powered equipment, smartphones, tablets, digital cameras, and audio devices where low noise and fast transient response are critical.
