MULTIFUNCTION VOLTAGE REGULATOR FOR CAR RADIO  
3 PROGRAMMABLE OUTPUTS:  
3 TO 11V (500mA);  
3 TO 11V (500mA);  
3 TO 7V (500mA) STANDBY  
OUT1 AND OUT2 WITH INDEPENDENT EN-  
ABLE CONTROL FOR STAND-BY MODE  
0.4A HIGH SIDE DRIVER  
LOAD DUMP PROTECTION  
THERMAL SHUTDOWN  
DESCRIPTION  
The L4943 contains a triple voltage regulator and  
a high side driver.  
Multiwatt 15  
ORDERING NUMBER:  
L4943  
In stand-by the output is active as long as possi-  
ble even when in thermal shutdown or under any  
other fault conditions.  
The STCAP pin allows the use of a reserve sup-  
ply capacitor that will hold enough energy for the  
5V Stand-by line to allow the µP to store data.
