Many of the new LDO regulators are optimized for low quiescent current (like 75 to 150 mA), and provide significant improvement over typical regulators which draw several milliamps.
If the load current increases to the limiting value, the current limiting circuitry will take control and force the load current to the set limiting value (overriding the voltage error amplifier). The voltage error amplifier can resume control only if the load current is reduced sufficiently to cause the current limiting circuits to release control. This is covered in detail in the "Current Limiting" section.
