The L4988 is a monolithic integrated 5V voltage regulator with a low drop voltage at currents up to 200mA. The output voltage regulating element consists in a p-channel MOS and the regulation is performed regardless of input voltage transients up to 40V. The high precision of the output voltage is obtained with a pre-trimmed reference voltage. The L4988 is protected against short circuit and an over-temperature protection switches off the device in case of extremely high power dissipa-tion. The L4988 is active when the Enable is high. State of the art features like reset and watchdog make this device particularly suitable to supply microprocessor systems in automotive applications.
