CJA1117-5.0中文资料至尚臻品数据手册PDF规格书

GENERAL DESCRIPTION

The CJ1117 is a series of low dropout three-terminal regulators with a dropout of 1.15V at 1A output current.

The CJ1117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1. 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 CJ1117 has an adjustable version, that can provide the output voltage from 1.25V to 5V with only 2 external resistors.

The CJ1117 series is available in the industry standard SOT-223,SOT-89,TO-220,TO-252 and TO-263 power packages.
