1A Low Dropout Positive Adjustable or Fixed-Mode Regulator
Description
The GJ1117A 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. GJ1117A is also well suited for other
applications such as VGA cards. GJ1117A 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

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 must be connected from this pin
to ground to insure stability.
The input pin of regulator. Typically a large storage capacitor 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.
