PRELIMINARY
C-MOS STEP-UP SWITCHING REGULATOR
■
GENERAL DESCRIPTION
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.
