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. 8-SOP 1 Internal Block Diagram OUT(1) INPUT(8) + PROGRAM (2) ERROR AMPLIFIER + FEEDBACK(7) C1 SHUTDOWN(3) + OFFSE TAP(6) FROM EXTERNAL INPUT SCP T ERROR COMPARATO 1.25V + COMPARATOR R REFERENCE TO EXTERNAL INPUT + GROUND(4) ERROR(5) ©2001 Fairchild Semiconductor Corporation LP2951.
