NJU7261 Series - 1 -Ver.2003-07-18 PRELIMINARY C-MOS STEP-UP SWITCHING REGULATOR ■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE The NJU7261 series is a C-MOS step-up switching regulator which contains accurate voltage reference, error amplifier, CR oscillator, control circuit, switching transistor, diode and resistor. The stand-by function is effective for low power consumption. The regulation voltage is fixed by internal circuits and the following line-up of different output voltages version are available. This series is suitable for portable equipment's or battery operated items because of its small packaged outline, low operating voltage and current. ■ FEATURES ■ PIN CONFIGULATION • Low Operating Voltage (1.0V min.) • Low Operating Current (5.0µA typ. / VOUT = 3.0V) • Low Stand-by Current (0.2µA max. / VOUT = 3.0V) • High Precision Output Voltage (±3% max.) • Wide Operating Voltage Range • Stand-by Function • CR Oscillator On-chip • Diode On-chip • Package Outline SOT89-5 • C-MOS Technology ■ LINE-UP ■ EQUIVALENT CIRCUIT Output Voltage (V) Line-Up 3.0 NJU7261U30 3.3 NJU7261U33 4.5 NJU7261U45 5.0 NJU7261U50 ■ TERMINAL DESCRIPTION No. Term.
