Description
The FAN1112 is a 1.2V low dropout three-terminal
regulator with 1A output current capability. The device has
been optimized for low voltage where transient response and
minimum input voltage are critical.
Current limit is trimmed to ensure specified output current
and controlled short-circuit current. On-chip thermal limiting
provides protection against any combination of overload and
ambient temperatures that would create excessive junction
temperatures.
Unlike PNP type regulators where up to 10% of the output
current is wasted as quiescent current, the quiescent current
of the FAN1112 flows into the load, increasing efficiency.
The FAN1112 regulator is available in the industry-standard
SOT-223 and TO-252 (DPAK) power packages.
