NJU7211 Series C-MOS 3-TERMINAL NEGATIVE VOLTAGE REGULATOR ■ GENERAL DESCRIPTION The NJU7211 series is a C-MOS 3-terminal negative voltage regulator which contains internal precision 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 NJU7211 series is suitable for battery operated items and battery back-up systems because of low operating current and low dropout voltage. ■ FEATURES • Low Operating Current (19μA typ.) • Wide Operating Voltage Range • Low Dropout Voltage (ΔVIO < 0.6V -3.0V output, IOUT = 20mA) (ΔVIO < 0.6V -5.0V output, IOUT = 40mA) • Small Temperature Coefficient of Output Voltage • Package Outline ( SOT-89) • C-MOS Technology ■ OUTPUT VOLTAGE LINE-UP Output Voltage SOT-89 Type -2.0V NJU7211U20 -3.0V NJU7211U30 -4.0V NJU7211U40 -5.0V NJU7211U50 ■ PACKAGE OUTLINE 3 12 NJU7221U (SOT-89) ■ TERMINAL DESCRIPTION No.
