NJU7221 Series HIGH PRECISION C-MOS 3-TERMINAL VOLTAGE REGULATOR Mi GENERAL DESCRIPTION The NJU7221 series is a high precision output voltage (42%) 3-terminal positive voltage regulator which contains internal accurate voltage reference, error am- plifier, control transistor and output voltage setting resistor. The regulation voltage is fixed by internal circuits Mi PACKAGE OUTLINE l 12 and the following line-up of different output voltage 123 versions are available. The NJU7221 series is suitable for battery operated NJU7221L NJU7221U items and battery back-up systems because of low operat- ing current and low dropout voltage. i FEATURES Mi TERMINAL DESCRIPTION @ High Precision Output Voltage +2% @ Low Operating Current 19uA typ @ Low Dropout Voltage AV10<0.6V @Io=100mA GND @ Wide Operating Voltage Range I @ Small Temperature Coefficient of Output Voltage @ Package Outline T0-92/SOT-89 @ C-M0S Technology Wi OUTPUT VOLTAGE LINE-UP Quiput Voltage | TO-92 Type | SOT-89 Type | Output Voltage | TO-92 Type SOT-89 Type +1.2V NJU7221L12 NJU7221U12 +3.2V NJU7221L32 NJU7221U32 +1.5V NJU7221L15 NJU7221U15 +3.5V NJU7221L35 NJU7221U35 +1.9V - NJU7221L19 NJU7221U19 +4.0V NJU7221L40 NJU7221U40 +2.0V NJU7221L20 NJU7221U20 +5.0V NJU7221L50 NJU7221U50 +2, 5V NJU7221L25 NJU7221U25 +5.2V NJU7221L52 NJU7221U52 +2.7V NJU7221L27% | NJU7221U27% +5. 5V NJU7221L55 NJU7221U55 +3.0V NJU7221L30 NJU7221U30 = = = Notel) The SOT-89 type name is different from the marking, so it refer to attached paper correspondence table.
