  • Wide input voltage range (2.7V to 10V)
  • Precision (trimmed) bandgap reference
  • Guaranteed specs for -40°C to +125°C
  • 1µA off-state quiescent current
  • Thermal overload protection

  • T0-252, SOT-223 and 6-Lead LLP packages
  • Enable pin (LP38693)

    • Description

    The LP38691/3 low dropout CMOS linear regulators provide tight output tolerance (2.0% typical), extremely low dropout voltage (250 mV @ 500mA load current, VOUT = 5V), and excellent AC performance utilizing ultra low ESR ceramic output capacitors.

    The low thermal resistance of the LLP, SOT-223 and TO-252 packages allow the full operating current to be used even in high ambient temperature environments.

    The use of a PMOS power transistor means that no DC base drive current is required to bias it allowing ground pin current to remain below 100 µA regardless of load current, input voltage, or operating temperature.

    Dropout Voltage: 250 mV (typ) @ 500mA (typ. 5V out).

    Ground Pin Current: 55 µA (typ) at full load.

    Precision Output Voltage: 2.0% (25°C) accuracy.

    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.
