Description
The GS1085 is a low dropout three terminal
regulator with 3A 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 1.8V, 2.5V, or 3.3V. 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 current and thermal limiting provides protection against any overload condition that would create excessive junction temperatures.
Features
Dropout Voltage 1.3V at 3A Output Current Fast Transient Response Line Regulation typically at 0.015% Load Regulation typically at 0.1% Internal thermal and current limiting Adjustable Output Voltage or Fixed 1.8V, 2.5V, 3.3V Standard 3-Pin Power Packages
