Description
The Six1084 is a low dropout three terminal regulator with 5A
output current capability. The output voltage is adjustable
with the use of a resistor divider. For fixed output voltage ver-
sions, the output voltage is internally set at 1.8V, 2.5V, or
3.3V. Dropout is guaranteed at a maximum of 1.4V at max-
imum output current. Its low dropout voltage and fast tran-
sient 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 5A 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
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 V
in
Range.
The specified limits also apply for the fixed voltage versions over the allowable input voltage range: Six1084-1.8 (3.2V - 7.0V), Six1084-2.5 (3.9V - 7.0V),
Six1084-3.3 (4.75V - 7.0V).
(2) To maintain the specified junction temperatures, low duty cycle pulse testing is required for most parameters.
