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.
Applications
• Post Regulator for Switching Supply
• Microprocessor Power Supplies
• Constant-Current Regulators
• Motherboard I/O Power Supplies

Notes:
(1) All parameters, except nominal output voltage are specified for the variable voltage version, allowing a wider Vin Range.
The specified limits also apply for the fixed voltage versions over the allowable input voltage range: GS1085-1.8 (3.2V - 7.0V), GS1085-2.5 (3.9V - 7.0V),
GS1085-3.3 (4.75V - 7.0V).
(2) To maintain the specified junction temperatures, low duty cycle pulse testing is required for most parameters.

Notes:
VREF = VOUT – VADJ = 1.25V (typ.)
VOUT = VREF x (1+R2/R1) + IADJ x R2
IADJ = 55µA (typ.)
