G1116
0.6A Low Dropout Positive Adjustable or Fixed-Mode Regulator
Description
The G1116 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. G1116 is also well suited for other
applications such as VGA cards. G1116 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

Function
A resistor divider from this pin to the Vout pin and ground sets the output voltage
(Ground only for fixed mode)
The output of the regulator. A minimum of 10uF capacitor (0.15 ESR 20 )
must be connected from this pin to ground to insure stability.
The input pin of regulator. Typically a large storage capacitor (0.15 ESR 20 )
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.

Note 1: See thermal regulation specifications for changes in output voltage due to heating effects. 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.
