Description
The FAN1616A, FAN1616A-1.8, -2.5, -3.3 and -5 are low
dropout three-terminal regulators with 0.5A output current
capability. These devices have been optimized for applica-
tions where transient response and minimum dropout 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
FAN1616A flows into the load, increasing efficiency.
The FAN1616A series regulators are available in the
industry-standard SOT-223 and TO-252 power packages.
