DESCRIPTION

The L4946 is a quad output low drop voltage

regulator. The four outputs are a low drop 10V at

125mA (VO1), a 8V at 250mA (VO2), a 5V at

200mA (VO3) and a low drop 5V st-by line at

100mA (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-

cay slowly giving the

µP time to store data. This

IC is designed for supplying microcomputer con-

trolled systems specially in automotive applica-

tions.
