DESCRIPTION
●The L4952 is a monolithic voltage regulator in an advanced BCD60II process with high efficient p-channel transistor. This device is optimized for Car Radio applications to obtain optimum per formance and supply system integration with high flexibility and minimum peripheral components.
●■ OPERATION SUPPLY VOLTAGE 9.5 TO 28V
●■ PEAK SUPPLY OVERVOLTAGE PULSE UP TO 52V (VS. GND)
●■ FIXED OUTPUT VOLTAGE OF 8.6 ± 0.2V AND OUTPUT CURRENT UP TO 150mA
●■ VERY LOW DROP OUTPUT STAGE WITH LOW OUTPUT VOLTAGE DIAGNOSTIC
●■ OUTPUT SHORT CIRCUIT AND THERMAL OVERLOAD PROTECTION
●■ VERY LOW STANDBY CURRENT (DEVICE DISABLED)
●■ TWO INTERNAL OUTPUT VOLTAGE SWITCHES WITH LOW DROPOUT FOR AM/FM SWITCHING
●■ DRIVER CIRCUIT FOR EXTERNAL HIGH SIDE SWITCH WITH DROP MONITORING
●■ ENABLE INPUT TO SWITCH ON THE DEVICE
●■ ADDITIONAL 10V VERY LOW DROP REGULATOR TO SUPPLY THE VARICAP
