长晶 CJA1117B-3.3 低压差线性稳压器 三端子可调或固定

INTRODUCTION

The CJA1117B-XXX is a series of low dropout three-terminal regulators with a dropout of 1.15V at 1A output current.

The CJA1117B-XXX series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandage. 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 CJA1117B-XXX has an adjustable version, that can provide the output voltage from 1.25V to 5V with only 2 external resistors.
