General Description
The NJM2839 is a positive/negative 2-channel low dropout voltage regulator featuring a low noise, high precision of ±1.5% (both channels), high ripple rejection ratio of 75dB (positive typ.),65dB (negative typ.), and 100mA output current (both outputs).It also offers useful functions of an ON/OFF control, thermal overload protection and short circuit current limit, and it can use ceramic capacitor of 1µF as an output capacitor. Further taking voltage output sequence into consideration, the NJM2839 provides an soft-start function and output shunt switch in negative voltage channel. It is available in a small surface mount 8-lead MSOP (VSP) package. It is suitable for a power supply circuit for CCD and others.
