■ GENERAL DISCRIPTION
●NJM128xx series are low dropout regulators which achieve high ripple
rejection, low noise and high speed response characteristics with bipolar
technology. Adjustable soft-start function is useful for reducing inrush current and controlling power-on sequence. Moreover the discharge function makes effective sequence control with the soft-start function. In addition, the reverse current protection makes external SBD unnecessary.
■ FEATURES
●Adjustable Soft-start Function
●Discharge Function
●Reverse Current Protection
●Operating Voltage Range 2.3V to 6.5V (Maximum rate 7V)
●Operating Temperature Range -40℃to-125℃
●Quiescent Current 145uA~400uA(Depends on each products)
●Output Current 200mA/300mA/500mA/1.0A
●Output Voltage Accuracy Vo±l.0%(Ta=25℃)
●ON/OFF Function
●Correspond to Low ESR Capacitor (MLCC) O.luF (min.)
●Thermal Shutdown Protection
●Over Current Protection
