NJU7201

NJU7201 Series C-MOS 3-TERMINAL POSITIVE VOLTAGE REGULATOR ■ GENERAL DESCRIPTION The NJU7201 series is a C-MOS 3-terminal positive voltage regulator which contains internal accurate 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 NJU7201 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 < 0.3V 1.2 to 1.5V output, IOUT = 0.5mA) (ΔVIO < 0.6V 2.5 to 3.5V output, IOUT = 20mA) (ΔVIO < 0.6V 4.0 to 5.5V 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 +1.2V NJU7201U12 +1.5V NJU7201U15 +2.5V +2.7V +3.0V +3.2V NJU7201U25 NJU7201U27 NJU7201U30 NJU7201U32 Output Voltage +3.5V +4.0V +4.5V +5.0V +5.2V +5.5V SOT-89 Type NJU7201U35 NJU7201U40 NJU7201U45 NJU7201U50 NJU7201U52 NJU7201U55 ■ PACKAGE OUTLINE 1 23 NJU7201U (SOT-89) ■ TERMINAL DESCRIPTION No. Description 1 GND 2 Input 3 Output ■ EQUIVALENT CIRCUIT VIN 2 3 VOUT GND 1 + - VREF Ver.2013-11-21 -1- NJU7201 Series ■ ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL Input Voltage Output Voltage Output Current Power Dissipation Operati...
