Description

The LP2951 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.
