L4989D013TR STMicroelectronics

L4989D, L4989MD Automotive low power voltage regulator Datasheet - production data Description The L4989M and L4989MD are monolithic integrated 5 V voltage regulators with a low drop voltage at currents up to 150 mA. The output voltage regulating element consists in a p-channel MOS and the regulation is performed regardless of input voltage transients up to 40 V. The high precision of the output voltage is SO-8 SO-20 obtained with a pre-trimmed reference voltage. The devices are protected against short circuit and an overtemperature protection switches off Features the devices in case of extremely high power AEC-Q100 qualified dissipation. Operating DC supply The L4989M and L4989MD watchdogs are active voltage range 5.6 V to 31 V when the Enable pin is high. Features like reset and watchdog make this devices particularly Very low quiescent current with watchdog suitable to supply microprocessor systems in disabled automotive applications. Precision output voltage (3%) Low drop voltage (180 mV typ at I = 150 mA) o Reset circuit sensing the output voltage down to 1 V Programmable reset delay with external capacitor Watchdog disable input Programmable watchdog timer with external capacitor Thermal shutdown and short circuit protection Wide temperature range (T = -40C to 150C) j Table 1.
