一,产品概述(General Description)
The JTM6209 series are highly accurate, low noise,LDO Voltage Regulators .On chip trimming adjusts the reference/output voltage to within ±2% accuracy. Internal protection features consist of output current limiting, safe operating area compensation, and thermal shutdown. The current limiter’s feedback circuit also operates as a short protect for the
output current limiter and the output pin. The CE function allows the output of regulator
to be turned off, resulting in greatly reduced power consumption. The JTM6209 series can operate with up to 18V input.
