Description
The LP2951 is an adjustable micro-power voltage regu-
lator suitable for battery-powered systems. This regula-
tor has various functions such as alarm that warns of a
low output voltage often due to falling batteries on the
input, the external shutdown enables the regulator to be
switched on and off, current and temperature limiting.
