Extremely tight line and load regulation.
Current limiting and thermal protection.
Adjustable output voltage or fixed at 1.5V,
1.8V, 2.5V, 3.3V.
Standard 3-pin power packages.
APPLICATIONS
Motherboard I/O Power Supplies.
Microprocessor Power Supplies.
High-Current Regulators.
Post-regulator for Switching Supplies.
DESCRIPTION
The SS6084 is a low-dropout three-terminal linear
regulator with 5A output current capability. The
output voltage is adjustable with a resistor divider or
fixed at 1.5V, 1.8V, 2.5V or 3.3V. Dropout voltage is
guaranteed to be a maximum of 1.4V at the
maximum output current. This low dropout voltage
and fast transient response make the SS6084 ideal
for low-voltage microprocessor applications. Current
and thermal limiting provide protection against
overload conditions that would create excessive
junction temperatures.

(1) C1 is needed if the device is
physically far from the filter
capacitors.
(2) C2 is required for stability.
