LDO Current Foldback/Current Limiter Circuits Tips
... In this table, most of the older Torex LDO's (XC6204, XC6219, etc) are of type A, where the current limiter circuit was added due to the lack of accuracy of the current foldback circuit. Then, around the year 2005, it became possible to use the foldback circuit as a current limiter too. So Torex int ...

MAX965–MAX970 Single/Dual/Quad, Micropower, Ultra-Low-Voltage, Rail-to-Rail I/O Comparators General Description
... Many comparators oscillate in the linear region of operation because of noise or undesired parasitic feedback. This tends to occur when the voltage on one input is equal or very close to the voltage on the other input. The MAX965–MAX970 have internal hysteresis to counter parasitic effects and noise ...
