NJM2842 Datasheet, PDF (1/11 Pages) New Japan Radio – Very Low Output Low Dropout Regulator

NJM2842
Very Low Output Low Dropout Regulator
GENERAL DESCRIPTION
The NJM2842 is a very low output voltage, low drop out
regulators.
It delivers up to 1A output current with the output voltage of
0.8 to 1.8V.
The use of an external bias voltage can improve the
transient response and the ripple rejection characteristics
while maintaining minimum input to output voltage.
