GS2905 500mA CMOS LDO Voltage Regulator
Product Description
The GS2905 series is a group of positive voltage output, three-pin regulators, that provide a high current even when the input/output voltage differential is small. Low power consumption and high accuracy is achieved through CMOS and programmable fuse technologies. Output voltage: 1.5V to 6.0V. The GS2905 consists of a high-precision voltage reference, an error correction circuit, and a current limited output driver. Transient response to load variations has improved in comparison to the existing series. The GS2905 incorporates both over-temperature and over-current protection. SOT-89 and SOT-223 packages are available.
