The supply current at no-load is 55µA. In the shutdown mode, the maximum supply current is less than 1µA. Operating voltage range of the G914X is from 2.5V to 5.5V. The over-current protection limit is set at 500mA typical and 400mA minimum. An over- temperature protection circuit is built-in in the G914X to prevent thermal overload. These power saving features make the G914X ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s. „ „ „ „ Ultra Low Output Noise⎯30µV (rms) Ultra Low 55µA No-Load Supply Current Ultra Low Dropout 70mV @ 50mA Load Guarantee 300mA Output Current Over-Temperature and Short-Circuit Protection Fixed Mode: 2.70V (G914A), 2.80V (G914B) 3.00V (G914C), 3.30V (G914D) 2.50V (G914E), 2.85V (G914F) 1.50V (G914G), 1.80V (G914H) Adjustable Mode: from 1.25V to 5.50V (G914Z) PSRR=70dB Max.
