Description
The KA78RLOO is an adjustable micro power voltage
regulator suitable for use in battery-powered systems. This
regulator has various functions such as alarm which warns of
a low output voltage, often due to falling batteries on the
input, the external shutdown which enables the regulator to
be switched on and off, current and temperature limiting.
