It uses an external N-channel pass FET — no internal switch — so the current rating is set by the MOSFET and sense resistor you pair with it.
Programmable protection thresholds
Four programmable features — current limit, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO) — let you set the trip points with external resistor dividers. The latched fault behaviour (LM5069MMX-1 variant) shuts the gate off on a fault and holds it off until the supply is cycled, which is the right response for applications where automatic retry could feed a sustained overcurrent.
No official successor is listed on the record. The LM5069MMX-2 variant shares the same base number and package but differs in fault response — verify the fault-handling behaviour needed for your design before cross-referencing.
