GS1117CST-3.3
GS1117CST-3.3 is 800mA Low Dropout Positive Adjustable Regulator manufactured by Vishay.
Description
The GS1117 is a low dropout three terminal regulator with 800m A 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.
