Features Description GM6350 is a group of positive voltage output, three - pin Maximum output current: 300mA regulators, that provide a high current even when the input/ Highly accurate: Output voltage ±2% output voltage differential is small. Low power consumption Low power consumption. and high accuracy is achieved through CMOS and pro- Over -Current and Over-Temperature grammable fuse technologies. Output voltage: 1.5V to 5.0V. protection Small input/ output differential: GM6350 consists a high-precision voltage reference, an er- 0.3V at 300mA ror correction circuit, and a current limited output driver. Transient response to load variations have improved in comparison to the existing series. GM6350 incorporates both over-temperature and overcurrent protection.
