SGM2211 20V, 500mA, Low Noise,Low Dropout Linear Regulator

PublishTime：2020-11-16

The SGM2211 is a low dropout linear regulator that operates from 2.7V to 20V and provides up to 500mA of output current. This high input voltage LDO provides wide output voltage range from 19V down to 1.2V rails that high performance analog and mixed signal circuits need. The SGM2211 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 SGM2211 is available in fixed output voltage versions and an adjustable version that allows the output voltage to range from 1.2V to (V-IN – V-DROP) via an external feedback divider. The SGM2211 regulator output noise is 9.3μV-RMS at 1.2V output voltage and 14μV-RMS at 5V output voltage.The SGM2211 is available in Green TDFN-2×2-6AL and SOT-23-5 packages. It operates over an operating temperature range of -40°C to +125°C.
