NJW4104 is a 45V Io=200mA ultra low quiescent

current low dropout regulator.

It achieves low quiescent current characteristics,

therefore it contributes to reduce current consumption

of applications.

Output Voltage is guaranteed ±2% under wide range

conditions: V

=Vo+1V to 40V, Io=0 to 200mA and

Ta=-40 C to 125 C.

Because of wide input voltage range and wide

operating temperature range, the NJW4104 is suitable

for various applications including automotive

applications.

● Automotive infotainment

● Automotive ECU unit

● Industrial equipment
