General Description

The NJM2841 is a low output voltage, low drop out regulators.It delivers up to 500mA output current with the output voltage of 0.8 to 2.5V.The use of an external bias voltage can improve the transient response and the ripple rejection characteristics while maintaining minimum input to output voltage.
