GENERAL DESCRIPTION
s
PACKAGE OUTLINE
The NJU7241 series are high precision ±2%, 60mA
output, C-MOS voltage regulators with standby function,
which contains internal accurate voltage reference, error
amplifier, control transistor, output voltage setting resistor,
short current protection circuit and standby circuit.
The fixed regulation voltages of internal circuits are as
NJU7241F
following line-up.
The NJU7241 series packed MTP5 and suitable for
battery-operated items, battery back-up systems, and es-
pecially control block of cellular phone system because of
low operating current and low dropout voltage.
