illustrate
National Semiconductor's FlexCap LDO features unique compensation, allowing any type of output capacitor with no limit on the use of minimum or maximum ESR. 而低压差线性稳压器LP38501 / 3系列工作于+2.7 V至+5.5 V输入电源。 These ultra-low dropout linear regulators respond very quickly to intervene in the load, which makes them suitable for changes in low voltage microprocessor applications. 在CMOS工艺开发（利用一个PMOS晶体管）时，LP38501 / 3具有低静态电流与负载电流的变化不大。
Ground pin current: 通常2毫安在3A的负载电流。
Disable mode: The enable pin is typically pulled low at 25 nA quiescent current.
Simplified compensation: As with any type of output capacitor, ESR is both stable.
Precision output: "A" with 1.5% VADJTolerance (25 ° C) and above line, load and temperature grade versions are available 3%.
