... Description GM6251 combines high accuracy with very low power consumption, and provides high output current even when the application requires extremely low input-output voltage dropout. GM6251 includes a precision voltage reference, an error correction circuit, over-temperature protection, and a current limited output driver. Fast transient response to load variations provides excellent stability under dynamic loads ...
