The NJU7261 series is a C-MOS step-up switching regulator which contains accurate voltage reference, error amplifier, CR oscillator, control circuit, switching transistor, diode and resistor. The stand-by function is effective for low power consumption. The regulation voltage is fixed by internal circuits and the following line-up of different output voltages version are available. This series is suitable for portable equipment's or battery operated items because of its small packaged outline, low operating voltage and current.
