L4946B - QUAD VOLTAGE REGULATOR WITH INHIBIT AND RESET

General Description

The L4946B is a quad output low drop voltage regulator.

The four outputs are a low drop 10V at 125mA (VO1), a 8.5V 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.
