STMicroelectronics L4988D
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.| Part No. | L4988D |

● Operating DC supply voltage range 5.6 V to 31 V
● Reset circuit sensing the output voltage down to 1V
● Programmable reset pulse delay with external capacitor
● Watchdog Table 1. Device summary The L4988 is protected against short circuit and an over-temperature protection switches off the device in case of extremely high power dissipation. 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.
