NJU7241 Series
High-Precision LDO 60mA C-MOS Voltage Regulator with Standby
s GENERAL DESCRIPTION s PACKAGE OUTLINE The NJU7241 series are high precision 2%, 60mA output, C-MOS voltage regulators with standby function, which contains internal accurate voltage reference, error amplifier, control transistor, output voltage setting resistor, short current protection circuit and standby circuit. The fixed regulation voltages of internal circuits are as NJU7241F following line-up. The NJU7241 series packed MTP5 and suitable for battery-operated items, battery back-up systems, and especially control block of cellular phone system because of low operating current and low dropout voltage. s FEATURES 2% * High Precision Output Voltage 20A typ. * Low Operating Current 0.1A typ. * Low Standby Current 0.2V typ. VOUT=3V * Low Dropout Voltage 55dB typ. @1kHz * Ripple Rejection * Standby Function * Small Temperature Coefficient of Output Voltage * Wide Operating Voltage Range MTP-5 * Package Outline * C-MOS Technology
