L4948 - QUAD VOLTAGE REGULATOR WITH INHIBIT AND RESET

Description

The L4948 is a quad output low drop voltage regulator.

All four outputs are low drop: 10V at 300mA (VO1), 8V at 400mA (VO2), 5V at 600mA (VO3) and a 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.
