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 output voltage versions, the output voltage is internally set at 2.5V, 2.85V, 3.3V or 5V. Dropout is guaranteed at a maximum 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.
Features
Dropout Voltage 1.2V at 800mA Output Current Fast Transient Response Line Regulation typically at 0.015% Load Regulation typically at 0.1% Internal thermal limiting Adjustable Output Voltage or Fixed 2.5V, 2.85V, 3.3V, 5V Standard 3-Pin Power Packages
