NJU7211L50

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 (∆VIO < 0.6V -3.0V output, IOUT = 20mA) (∆VIO < 0.6V -5.0V output, IOUT = 40mA) • Small Temperature Coefficient of Output Voltage • Package Outline (TO-92/SOT-89) • C-MOS Technology ■ OUTPUT VOLTAGE LINE-UP Output Voltage TO-92 Type -2.0V NJU7211L20 -3.0V NJU7211L30 -4.0V NJU7211L40 -5.0V NJU7211L50 ■ PACKAGE OUTLINE NJU7211L(TO-92) NJU7211U(SOT-89) ■ TERMINAL DESCRIPTION No. Description 1 Output 2 GND 3 Input SOT-89 Type NJU7211U20 NJU7211U30 NJU7211U40 NJU7211U50 ■ EQUIVALENT CIRCUIT GND 2 VREF + VIN 3 Ver.2003-07-23 1 VOUT -1- NJU7211 Series ■ ABSOLUTE MAXIMUM RATINGS PARAMETER Input Voltage SYMBOL (Ta = 25ºC) RATINGS UNIT VIN -14 V Output Voltage VOUT GND+0.3 to VIN-0.3 V Output Current IOUT 100 mA Power Dissipation PD 500 (TO-92) 300 (SOT-89) Operating Temperature Topr -25 to + 75 ºC mW Storage Temperature Tstg -40 to +125 ºC Soldering Temperature / Time Tsold 260ºC/10 sec - ■ ELECTRICAL CHARACTERISTICS -2.0V Version PARAMETER Output Voltage Dropout Voltage Input Voltage Operating Current （CIN = Co = 0.1µF, Ta = 25°C) SYMBOL VOUT ∆VIO VIN IQ Load Regulation ∆VOUT / ∆IOUT Line Regulation ∆VOUT / (∆VIN･VOUT) CONDITION MIN.
