  • Description

    The NJW4106 is a 45 V, Io = 500 mA fast transient response low dropout regulator. This device achieves fast transient response and offers stable output voltage even at line or load fluctuations. The output voltage can be adjusted from 2.5 V to 16 V. The NJW4106 provides outstanding high ADJ voltage accuracy that guaranteed 1.24 V ±1.0% under the conditions of VIN = Vo + 1 V to 40 V and Io = 0 mA to 500 mA. Moreover, wide operating voltage and wide operating temperature make the NJW4106 ideal for automotive accessories or applications that require high reliability.
