General Description
National's FlexCap LDO's feature unique compensation that allows the use of any type of output capacitor with no limits on
minimum or maximum ESR. The LP38501/3 series of low-dropout linear regulators operates from a +2.7V to +5.5V input supply.
These ultra low dropout linear regulators respond very quickly to step changes in load, which makes them suitable for low
voltage microprocessor applications. Developed on a CMOS process, (utilizing a PMOS pass transistor), the LP38501/3 has low
quiescent current that changes little with load current.
Ground Pin Current: Typically 2 mA at 3A load current.
Disable Mode: Typically 25 nA quiescent current when the Enable pin is pulled low.
Simplified Compensation: Stable with any type of output capacitor, regardless of ESR.
Precision Output: "A" grade versions available with 1.5% VADJ tolerance (25°C) and 3% over line, load and temperature.

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.
