HIGH PRECISION C-MOS 3-TERMINAL VOLTAGE REGULATOR
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJU7221 series is a high precision output voltage(±2%)
3-terminal positive voltage regulator which contains internal accurate
voltage reference, error amplifier, control transistor and output
voltage setting resistor.
The regulation voltage is fixed by internal circuits and the following
line-up of different output voltage versions are available.
The NJU7221 series is suitable for battery operated items and
battery back-up systems because of low operating current and low
dropout voltage.
■ FEATURES ■ TERMINAL DESCRIPTION

• Low Dropout Voltage (ΔVIO < 0.6V, IO = 100mA)
• Wide Operating Voltage Range
• Small Temperature Coefficient of Output Voltage
• Package Outline ( SOT-89)
• C-MOS Technology
