Description
The RC1616 and RC1616-2.5, -3.3 and -5 are low dropout
three-terminal regulators with 0.5A output current capability.
These devices have been optimized for low voltage where
transient response and minimum input voltage are critical.
The 5V version is designed also to be used in USB Hub and
Motherboard applications.
On-chip thermal limiting provides protection against any
combination of overload and ambient temperature that
would create excessive junction temperatures.
Unlike PNP type regulators where up to 10% of the output
current is wasted as quiescent current, the bias current of the
RC1616 flows into the load, increasing efficiency.
The RC1616 series regulators are available in the industry-
standard SOT-223 and TO-252 power packages.
