ISSUED DATE :2005/04/18 REVISED DATE :2006/06/05B G M 111 6 0.6A Low Dropout Positive Adjustable or Fixed-Mode Regulator Description The GM1116 is a low dropout at positive adjustable or fixed-mode regulator with minimum of 0.6A output current capability. 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 logic supply. GM1116 is also well suited for other applications such as VGA cards. GM1116 is guaranteed to have lower than 1.3V dropout at full load current making it ideal to provide well regulated outputs of 1.25V to 5.0V with up to 12V input supply. Features 1.3Vmaximum dropout full load current Fast transient response Output current limiting Built-in thermal shutdown Good noise rejection 3-Terminal Adjustable or Fixed 1.5V,1.8V,2.5V,3.3V,5.0V Applications PC peripheral Communication Package Dimensions SOT-89 REF.

A minimum of 10uF capacitor (0.15 ESR 20 ) must be connected from this pin to ground to insure stability. ESR 20 ) The input pin of regulator. Typically a large storage capacitor (0.15 is connected from this pin to ground to insure that the input voltage does not sag below the minimum dropout voltage during the load transient response. This pin must always be 1.3V higher than Vout in order for the device to regulate properly.

Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead =1/18” from the package. Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 3W. Power dissipation is determined by the difference between input and output and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range. 3/4 ISSUED DATE :2005/04/18 REVISED DATE :2006/06/05B Characteristics Curve I load=600mA Important Notice: All rights are reserved.
