L4948
DESCRIPTION
The L4948 is a quad output low drop voltage regulator. All four outputs are low drop: 10V at 300m A (VO1), 8V at 400m A (VO2), 5V at 600m A (VO3) and a 5V st-by line at 100m A (VO4). The IC includes a monitoring circuit to warn if a low voltage or no voltage condition is occurring. VO1,2,3 are off during st-by mode. The STCAP pin allows the battery voltage to de BLOCK DIAGRAM MULTIPOWER BCD TECHNOLOGY
Multiwatt 11 ORDERING NUMBER: L4948 cay slowly giving the µP time to store data. This IC is designed for supplying microputer controlled systems specially in automotive applications.
