长晶小封装 CJT1117B-1.8 低压差线性稳压器

　　INTRODUCTION

　　The CJT1117B-XXX is a series of low dropout three-terminal regulators with a dropout of 1.15V(typ.) at 1A output current.

　　The CJT1117B-XXX series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap. reference to assure output voltage accuracy to be within 1.5%. 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 CJT1117B-XXX has an adjustable version, th at can provide the output voltage from 1.25V to 5V with only 2 external resistors.
