NJU7222

NJU7222 Series www.DataSheet4U.com HIGH PRECISION AND HIGH OUTPUT CURRENT C-MOS 3-TERMINAL VOLTAGE REGULATOR ■ GENERAL DESCRIPTION The NJU7222 series is a high precision output voltage (±2%) and high output current C-MOS 3-terminal positive voltage regulator which contains internal accurate voltage reference, error amplifier, control transistor, output voltage setting resistor and short current protection circuit. The regulation voltage is fixed by internal circuits and the following line-up of different output voltage versions are available. The short current protection circuit prevents destruction of a element by careless great current output in short circuit. The NJU7222 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% High Output Current IO = 100mA Low Operating Current 20μA typ Low Dropout Voltage ΔVIO < 0.6V @IO = 100mA Wide Operating Voltage Range Small Temperature Coefficient of Output Voltage Short Current Protection Circuit Package Outline SOT-89 C-MOS Technology ■ PACKAGE OUTLINE PRELIMINARY 3 12 NJU7222U (SOT-89) ■ TERMINAL DESCRIPTION No. Description 1 GND 2 Input 3 Output ■ OUTPUT VOLTAGE LINE-UP Output Voltage SOT-89 Type +3.0V NJU7222U30 +3.3V NJU7222U33 +5.0V NJU7222U50 Note1) The SOT-89 type name is different from the marking, so it refer to attached paper correspondence table. ■ EQUIVALENT CIRCUIT Ver.2007-...
