NJU7261 - JRC

NJU7261 C-MOS STEP-UP SWITCHING REGULATOR

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 voltage.
