  • 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
  • Custom voltages available

    • Description

    The LP2985LV is a 150 mA, fixed-output voltage regulator designed to providehigh performance and low noise in applications requiring output voltages ≤ 2.0V.

    Using an optimized VIP (Vertically Integrated PNP) process, the LP2985LV delivers unequalled performance in all specifications critical to battery-powered designs:

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

    Enhanced Stability: The LP2985LV is stable with output capacitor ESR as low as 5 mΩ, which allows the use of ceramic capacitors on the output.

    Sleep Mode: Less than 1 µA quiescent current when ON/OFF pin is pulled low.

    Smallest Possible Size: micro SMD package uses absolute minimum board space.

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

    Low Noise: By adding a 10 nF bypass capacitor, output noise can be reduced to 30 µV (typical).


    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.
