The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high speed bus termination and low current 3.3V/2.5V or 3.3V/1.8V logic supply. GSC1120 series and guaranteed to have <1.3V dropout at full load current making it ideal to provide well regulated outputs dual channels with up to 18V input supply. Features Pin Descriptions Name GND 1/2 1.3Vmaximum dropout at full load current Fast transient response Output current limiting for each channel Built-in thermal shutdown each channel Good noise rejection Dual output A: ch1=3.3V, ch2=2.5V B: ch1=3.3V, ch2=1.8V PC peripheral Communication Function Ground 3.3V (Vout1) The output of the regulator. A minimum of 10 F capacitor 2.5V/1.8V (0.15 ESR 20 ) must be connected from this pin to ground to insure stability. (Vout2) Vin 1/2 The input pin of regulator. Typical a large storage capacitor (0.15 ESR 20 ) is connected form this pin to ground. Applications Package Dimensions REF. A B C D E F Millimeter Min.
