  • The L5050S is a 5 V low dropout linear voltage regulator suitable for automotive applications, available in a SO-8 package. The LDO delivers up to 50 mA of load current, and consumes as low as 5 μA of quiescent current with device disabled. High output voltage accuracy (±2%) is kept over wide temperature range, line and load variation. Enable feature allows output enabling or disabling. The maximum input voltage is 40 V. The regulator output current is internally limited and the device is protected against short circuit, overload and over temperature conditions. In addition, only low value ceramic capacitor on output is required for stability.

    Key Features

    • AEC-Q100 qualified
    • Operating DC supply voltage range 5.6 V to 40 V
    • Low dropout voltage
    • Low quiescent current consumption
    • Precision output voltage 5 V ±2%
    • Enable input for enabling/disabling the voltage regulator
    • Thermal shutdown and short circuit protection
    • Wide temperature range (Tj = -40°C to 150°C)
