NJU7222 Series 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 ∆VIO < 0.6V @IO = 100mA • Wide Operating Voltage Range • Small Temperature Coefficient of Output Voltage • Short Current Protection Circuit • Package Outline TO-92/SOT-89 • C-MOS Technology ■ PACKAGE OUTLINE PRELIMINARY NJU7222L NJU7222U ■ TERMINAL DESCRIPTION No. Description 1 GND 2 Input 3 Output ■ OUTPUT VOLTAGE LINE-UP Output Voltage TO-92 Type SOT-89 Type +3.0V NJU7222L30 NJU7222U30 +3.3V NJU7222L33 NJU7222U33 +5.0V NJU7222L50 NJU7222U50 Note1) The SOT-89 type name is different from the marking, so it refer to attached paper correspondence table. ■ EQUIVALENT CIRCUIT Ver.2003-07-18 -1- NJU7222 Series ■ ABSOLUTE MAXIMUM RATINGS PARAMETER Input Voltage Output Voltage Output Current Power Dissipation Operating Temperature Range Storage Temperature Range SYMBOL VIN VOUT IOUT PD Topr Tstg RATINGS 15 GND-0.3 to VIN+0.3 200 500 (TO-92) 300 (SOT-89) -25 to + 75 -40 to +125 (Ta = 25ºC) UNIT V V mA mW ºC ºC ■ ELECTRICAL CHARACTERISTICS +3.0V Version PARAMETER Output Voltage Dropout Voltage Input Voltage Operating Current Load Regulation Line Regulation SYMBOL VOUT ∆VIO VIN IDD1 ∆VOUT ∆IOUT (CIN = CO = 0.1µF, Ta = 25°C) CONDITION VIN = 5.0V, IOUT = 70mA IOUT = 50mA VIN = 5.0V VIN = 5.0V, IOUT = 1 to 100mA MIN. 2.85 TYP. 3.00 0.4 20 120 0.1 MAX. 3.15 0.6 14 30 160 UNIT V V V µA mV %/V ∆VOUT VIN = 4.0 to 12.0V ∆VIN ⋅ VOUT +3.3V Version PARAMETER Output Voltage Dropout Voltage Input Voltage Operating Current Load Regulation Line Regulation SYMBOL VOUT ∆VIO VIN IDD1 ∆VOUT ∆IOUT (CIN = CO = 0.1µF, Ta = 25°C) CONDITION VIN = 5.3V, IOUT = 70mA IOUT = 50mA VIN = 5.3V VIN = 5.3V, IOUT = 1 to 100mA MIN. 3.135 TYP. 3.300 0.4 20 120 0.1 MAX. 3.465 0.6 14 30 160 UNIT V V V µA mV %/V ∆VOUT VIN = 4.3 to 12.0V ∆VIN ⋅ VOUT +5.0V Version PARAMETER Output Voltage Dropout Voltage Input Voltage Operating Current Load Regulation Line Regulation SYMBOL VOUT ∆VIO VIN IDD1 ∆VOUT ∆IOUT (CIN = CO = 0.1µF, Ta = 25°C) CONDITION VIN = 7.0V, IOUT = 70mA IOUT = 100mA VIN = 7.0V VIN = 7.0V, IOUT = 1 to 100mA MIN. 4.75 TYP. 5.00 0.3 20 120 0.1 MAX. 5.25 0.6 14 30 160 UNIT V V V µA mV %/V ∆VOUT VIN = 6.0 to 12.0V ∆VIN ⋅ VOUT ■ MEASUREMENT CIRCUIT [CAUTION] The specifications on this databook are only given for information , without any guarantee as regards either mistakes or omissions.
