L4952D Datasheet PDF - ST Microelectronics

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
