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. G5M1119 is also well suited for other applications such as VGA cards. G5M1119 is guaranteed to have <1.3V dropout at full load current making it ideal to provide well regulated fixed outputs of 1.5V to 12V with up to 18V input supply. The G5M1119 offers a TTL-Logic compatible enable pin.

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 5W. Power dissipation is determined by the input/output difference and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range. Note 3: Quiescent current is defined as the minimum output current required in maintaining regulation. At 12V input/output differential the device is guaranteed to regulate if the output current is greater than 10mA.
