● Low Noise:
The SGM2209 is a low dropout linear regulator that operates from -2.7V to -24V and provides up to -500mA of output current. This high input voltage LDO is a high performance regulator to provide wide output voltage range from -1.2V down to -23V that high performance analog and mixed signal circuits need. The SGM2209 provides high PSRR, low noise and excellent line and load transient responses with a small 2.2μF ceramic output capacitor. These features are very important for noise sensitive circuits.
The SGM2209 is available in fixed output voltage versions and an adjustable version that allows the output voltage to range from -1.2V to (-VIN + VDROP) via an external feedback divider.
The SGM2209 regulator output noise is 10.5μVRMS at -1.2V output voltage and 16μVRMS at -5.0V output voltage. It provides maximum flexibility that the enable logic is capable of interfacing with positive or negative logic levels.The SGM2209 is available in Green TDFN-2×2-6AL, TDFN-3×3-8L and SOT-23-5 packages.
