SS6117AG
1A Low-Dropout Positive Regulator
FEATURES
Dropout voltage 1.3V at 1A output current.
Fast transient response.
Line regulation typically at 0.015%.
Load regulation typically at 0.1%.
Current-limiting and thermal protection.
Adjustable output voltage or fixed at 1.8V, 2.5V,
2.85V, 3.3V, 5V.
APPLICATIONS
Active SCSI termination.
Battery chargers.
Constant-current regulators.
Post regulator for switching supplies.
DESCRIPTION
The SS6117AG is a low-dropout three-terminal
regulator with 1A output current capability. The
output voltage is adjustable with the use of a
resistor divider or fixed at 1.8V, 2.5V, 2.85V, 3.3V,
or 5V. Dropout voltage is guaranteed to be a
maximum of 1.5V at the maximum output
current. The low dropout voltage and fast transient
response make this device ideal for low voltage
microprocessor applications. The current-limiting
and thermal protection reduce the risk that an
overload condition might create excessive junction
temperatures.
