产品概述

描述

The L4940 series of three-terminal positive regulators is available in TO-220 and D²PAK packages and with several fixed output voltages, making it useful in a wide range of industrial and consumer applications. Thanks to their very low input/output voltage drop, these devices are particularly suitable for battery-powered equipment, reducing consumption and prolonging battery-life. Each type employs internal current limiting, anti-saturation circuit, thermal shutdown and safe area protection.
  • 所有功能

    • Precise 5, 8.5, 12 V outputs
    • Low dropout voltage (450 mV typ. at 1 A)
    • Very low quiescent current
    • Thermal shutdown
    • Short-circuit protection
    • Reverse polarity protection
