What this LDO does on an automotive board
The MAX16910CASA8/V+ is a single-output positive LDO regulator from Analog Devices, qualified to AEC-Q100 for automotive applications. It delivers up to 200 mA from a 30 V maximum input.
Dropout, quiescent current, and what they mean for the rail
Maximum dropout voltage is 0.6 V at 200 mA. The 30 µA quiescent current holds across the temperature range. Enable and reset control features let the system sequence the rail.
Protection and package
Built-in over-temperature and short-circuit protection cover the common failure modes on a board that sees thermal cycling and vibration. The 8-SOIC with exposed pad (SOIC-EP) needs a thermal via pattern under the pad to pull heat into the PCB copper — the tab is the main thermal path, not the leads. Surface-mount assembly keeps the board compatible with standard reflow profiles.
Lifecycle and sourcing reality
It is ROHS3 compliant. No last-time-buy or obsolescence risk on this code today.
