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.
