NJM11100
Adjustable Low Dropout Regulator w/Reverse Current Protection
GENERAL DESCRIPTION
The NJM11100 is a 240mA output low dropout adjustable type
voltage regulator. The available setting voltage range is very
wide from 1.3V to 17V. This product has Reverse Current
Protection without external SBD. Advanced Bipolar technology
achieves low noise, high ripple rejection and high supply voltage.
It is suitable for various applications such as car AVN, any
consumer products and so on.
