Fixed 5V rail, 400 mA — what it handles
The LM2937IMP-5.0/NOPB is a fixed 5V positive-output LDO regulator from Texas Instruments, delivering up to 400 mA.
Dropout and quiescent current — the headroom numbers
Maximum dropout is 1 V at 50 mA load. Quiescent current is 2 mA typical, with a supply current max of 20 mA.
On-chip protection covers over-temperature, reverse polarity, and short-circuit conditions — the sort of ruggedness expected in an automotive or industrial environment.
Package and mounting — SOT-223
Housed in a SOT-223-4 surface-mount package (TO-261-4 equivalent).
