| NJU7221 Series www..com HIGH PRECISION C-MOS 3-TERMINAL VOLTAGE REGULATOR GENERAL DESCRIPTION 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 * High Precision Output Voltage (2%) * Low Operating Current (19A typ.) * Low Dropout Voltage (VIO < 0.6V, IO = 100mA) * Wide Operating Voltage Range * Small Temperature Coefficient of Output Voltage * Package Outline ( SOT-89) * C-MOS Technology OUTPUT VOLTAGE LINE-UP Output Voltage SOT-89 Type Output Voltage SOT-89 Type +1.2V NJU7221U12 +3.2V NJU7221U32 +1.5V NJU7221U15 +3.5V NJU7221U35 +1.9V NJU7221U19 +4.0V NJU7221U40 +2.0V NJU7221U20 +5.0V NJU7221U50 +2.5V NJU7221U25 +5.2V NJU7221U52 +2.7V NJU7221U27* +5.5V NJU7221U55 +3.0V NJU7221U30 Note1) The SOT-89 type name is different from the marking, so it refer to attached paper correspondence table.
