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 from 0.8V 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.
The NJM2842 suitable for constant-voltage source such as
CPU, DSP and ASIC.
