产品概述

描述

The L4993 is a monolithic integrated 5 V Voltage regulator 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 L4993 is protected against short circuit and an over-temperature protection switches off the device in case of extremely high power dissipation. The L4993 watchdog 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.

  • 所有功能

    • Operating DC supply voltage range 5.6 V to 31 V
    • Reset circuit sensing the output voltage down to 1 V
    • Programmable reset pulse delay with external capacitor
    • Watchdog
    • Programmable watchdog timer with external
    • Enable input for enabling/disabling the watchdog functionality
    • Thermal shutdown and short circuit protection
    • Wide temperature range (Tj = -40°C to 150°C)
