1A Low Dropout Voltage Regulator
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
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
