GJ1116

ISSUED DATE :2006/06/06 REVISED DATE : The GJ1116 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. GJ1116 is also well suited for other applications such as VGA cards. GJ1116 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. 0.6A Low Dropout Positive Adjustable or Fixed-Mode Regulator Description G J 111 6 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 & peripheral PC &Communication Package Dimensions TO-252 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.
