Update: 30 September, 2023
The L4989D 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 obtained with a pre-trimmed reference voltage. The devices are protected against short circuit and an overtemperature protection switches off the devices in case of extremely high power dissipation. Features like reset and watchdog make this devices particularly suitable to supply microprocessor systems in automotive applications.
