  • Description

    The NJW4184 is a high voltage and low current consumption low dropout regulator. It has two lineups as A version (built-in ON/OFF function type) and B version (3-terminal / compatible with 78L/Mseries). The NJW4184 is mounted in SOT-89-3/5, TO-252-3/5 packages and corresponded to Low ESR capacitor (MLCC). The wide input range makes the NJW4184 suitable for a Car accessory, industrial supplies, battery equipment and various applications.
