NJU7261 Series

PRELIMINARY

C-MOS STEP-UP SWITCHING REGULATOR

■ GENERALDESCRIPTION

■ PACKAGE OUTLINE

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.
