NJM2839 - JRC

NJM2839 POSITIVE/NEGATIVE 2CH LOW DROPOUT VOLTAGE REGULATOR

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 .
