The HGSEMI HG7150M3-1/TR linear voltage regulator is a low dropout (LDO) regulator packaged in a standard SOT-23-3 (surface-mount, three-pin) package. The device is designed to provide a low noise output voltage from 1.2V to 17V, with a maximum current of 500mA. The device is RoHS-compliant, indicating that it is made with lead-free and halogen-free materials that meet or exceed the requirements set by the European Restriction of Hazardous Substances directive (RoHS). It also meets other industry standards, such as AEC-Q100 for automotive applications. Features include short-circuit protection, thermal shutdown, and an input voltage range from 2.7V to 24V.
