Features

  • Guaranteed 150 mA output current
  • Smallest possible size (SOT-23 package)
  • Requires minimum external components
  • Stable with low-ESR output capacitor
  • Low ground pin current at all loads
  • Output voltage accuracy 1% (A Grade)
  • High peak current capability
  • Wide supply voltage range (16V max)
  • Low ZOUT: 0.3Ω typical (10 Hz to 1 MHz)
  • Overtemperature/overcurrent protection
  • −40°C to +125°C junction temperature range

    • Description

    The LP2983 is a 150 mA, fixed-output voltage regulator designed to provide tight voltage regulation in applications with output voltages ≤ 1.2V.

    Using an optimized VIP (Vertically Integrated PNP) process, the LP2983 delivers unequalled performance in all critical specifications:

    Ground Pin Current: Typically 825 µA @ 150 mA load, and 75 µA @ 1 mA load.

    Enhanced Stability: The LP2983 is stable with output capacitor ESR down to zero, which allows the use of ceramic capacitors on the output.

    Smallest Possible Size: SOT-23 package uses absolute minimum board space.

    Precision Output: 1% tolerance output voltages available (A grade).


    Applications

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
