STMicroelectronics L4989D
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 obtained with a pre-trimmed reference voltage.| Part No. | L4989D |

DESCRIPTION
The devices are protected against short circuit and an overtemperature protection switches off the devices in case of extremely high power dissipation. The L4989M and L4989MD watchdogs are active when the Enable pin is high.FEATURES
like reset and watchdog make this devices particularly suitable to supply microprocessor systems in automotive applications. Package SO-8 SO-20 Table 1.
