NJM2839
POSITIVE/NEGATIVE 2CH LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
The NJM2839 is a positive/negative 2ch low dropout
voltage regulator. Advanced bipolar technology achieves low
noise, high precision voltage and high ripple rejection.
Negative output CH has built into soft-start and shunt SW
functions.
Positive/Negative Dual output, 1.0µF Output capacitor
and small package can make NJM2839 suitable for power
supply for CCD of portable item.
