Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.
Please
email any questions regarding the system integration to

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.
