SERIES
1A Low Dropout Voltage Regulator
GENERAL DESCRIPTION
FEATURES
The CHC1117 is a series of low dropout three-terminal
regulators with a dropout of 1.4V at 1A output current.
The CHC1117 series provides current limiting and
thermal shutdown. Its circuit includes a trimmed
bandgap reference to assure output voltage accuracy
to be within 2% for 1.5V, 1.8V, 2.5V, 3.3.V 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 CHC1117 has an adjustable version that can
provide the output voltage from 1.25V to 8V with only
two external resistors.
The CHC1117 series is available in the industry
standard and SOT223 power packages.
