PRELIMINARY
C-MOS STEP-UP SWITCHING REGULATOR
■ GENERALDESCRIPTION
■ PACKAGE OUTLINE
The NJU7262 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 operating clock is prepared on-chip or is available to input
from external, and the stand-by function is effective for low power
consumption.
NJU7262MXX
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.
