Description
The GS1117 is a low dropout three terminal regulator with
800mA output current capability. The output voltage is
adjustable with the use of a resistor divider. For fixed out-
put voltage versions, the output voltage is internally set at
2.5V, 2.85V, 3.3V or 5V. Dropout is guaranteed at a maxi-
mum of 1.4V at maximum output current. Its low dropout
voltage and fast transient response make it ideal for low
voltage microprocessor applications. Internal thermal limiting
provides protection against any overload condition that
would create excessive junction temperatures.
Applications
• SCSI-2 Active Terminator
• Post Regulator for Switching Supply
• Battery Chargers
• Constant-Current Regulators
• PC Add-On Card
