NJM2842U2-015

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.
