How to select this device

LDO or buck?

When the voltage drop times the current exceeds roughly 0.5 W, switch to a buck — thermal budget in a sealed ECU is usually the deciding factor.

Why quiescent current matters?

Always-on nodes drain the battery during parking. Single-digit microamp IQ parts measurably extend standby time across a vehicle fleet.
