■GENERAL DESCRIPTION
The NJW4107 is a 45V, Io=300mA fast response low
dropout regulator. It achieves fast transient response,
therefore it provides stable output voltage at line/load
fluctuations.
Output voltage accuracy is guaranteed 1.5% under
wide range conditions: V
IN
=Vo+1V to 40V, Io=0mA to
300mA and Ta=-40 C to 125°C.
Because of wide input voltage range and wide
operating temperature range, the NJW4107 is suitable
for various applications including automotive
applications.
