1A Low Dropout Positive Adjustable or Fixed-Mode Regulator
Description
The GM1117A is a low dropout at positive adjustable or fixed-mode regulator with minimum of 1A 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. GM1117A is also well
suited for other applications such as VGA cards. GM1117A is guaranteed to have lower than 1.4V dropout at
full load current making it ideal to provide well-regulated outputs of 1.25 to 5.0 with 6.4V to 12V input supply.
Features
1.4Vmaximum dropout full load current
Fast transient response

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 in input and output and the output current. Guaranteed maximum power dissipation will
not be available over the full input/output range.
