GS1117A

1A Low Dropout Voltage Regulator Product Description The GS1117A is a low dropout three-terminal regulator with 1A output current capability. In order to obtain lower dropout voltage and fast transient response , which is critical for low voltage applications. The GS1117A has been optimized. The device is available in an adjustable version and fixed output voltage of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V. Dropout voltage is guaranteed at a maximum of 1.3V at 1A. Current limit is trimmed to ensure specified output current and controlled short circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. The GS1117A is available in the three leads SOT-89, SOT-223 and TO-252 surface mount packages.
