NJU7870

The NJU7870 is designed as one kind of voltage tripler incorporated CR oscillator, voltage converter, reference voltage circuit and coltage regulator that can generates triple or double negative voltage of an operating voltage ranging from -2.6V to -6V. The application circuit of tripler NJU7870 requires three capacitors and doubler requires only two capacitors. Furthermore, any kind of output voltage is available by the internal voltage regulator.

Features of the NJU7870 are:(1)triple / double voltage output;(2)operating voltage: -2.6 V to -6.0 V;(3)high-efficiency voltage conversion rate: 95%;(4)high output current: max 20 mA;(5)CR oscillator on-chip;(6)output-off function by external signal: ON / OFF of Vreg;(7)package outline: DIP/DMP/SSOP 14. The absolute maximum ratings of the NJU7870 can be summarized as:(1)supply voltage: 12 V;(2)operating supply voltage range: 4 to 8 V;(3)detector input voltage: 1.0 Vp-p;(4)input voltage: 1.0 Vp-p;(5)mute function: -0.5 to 5.0 Vpk;(6)operating temperature range: -20 to +75;(7)storage temperature range: -40 to +125.
