Product overview

Description

L5050 is a 5 V low dropout linear voltage regulator suitable for automotive applications, available in single (L5050S) or dual isolated (L5050SD) linear output voltage in a SO-8 package. The LDO delivers up to 50 mA (2x50 mA for the dual version) of load current and consumes as low as 5 μA (per each output in L5050SD) of quiescent current with device disabled. High output voltage accuracy (±2%) is kept over wide temperature range, line and load variation. Enable features (two enables for the dual version) allow enabling or disabling each output. 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.
  • All 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%
    • Dual electrically isolated voltage regulators (only for L5050SD)
    • Enable input for enabling/disabling the voltage regulator
    • Thermal shutdown and short circuit protection
    • Wide temperature range (Tj = -40 °C to 150 °C)
