FS1084
1. General Description
The FS1084 is a series of low dropout three-terminal
regulators with a dropout of 1.5V at 1Aoutput
current.
The FS1084 series provides current limiting and
thermal shutdown. Its circuit includes a trimmed
band gap reference to assure output voltage
accuracy to be within 2% for 1.8V, 3.3V and
adjustable versions. Current limit is trimmed to
ensure specified output current and controlled
short-circuit current. On-chip thermal shutdown
provides protection against any combination of
overload and ambient temperature that would create
excessive junction temperature.
The FS1084 has an adjustable version that can
provide the output voltage from 1.25V to 12V with
only two external resistors.
The FS1084 series is available in the industry
standard TO263-3L power package.
2. Features
Input voltage up to 18V.
1.5V maximum dropout at full load current
Fast transient response.
Output current limiting
Built-in thermal shutdown
Good noise rejection
3-Terminal Adjustable or Fixed 1.8V, 3.3V
