Fixed 1.1V automotive LDO — what the AEC-Q100 grade means for the BOM
The TLV73311PQDBVRQ1: AEC-Q100 qualified positive-output LDO regulator delivering a fixed 1.1V at 300mA, in a SOT-23-5 package.
Protection set — built-in, no external supervisor needed
The TLV73311PQDBVRQ1 integrates over-current, over-temperature, and under-voltage lockout (UVLO) protection. For a simple point-of-load rail feeding a 1.1V core, this removes the need for a separate supervisory IC or reset generator. The Enable pin allows the system MCU or power-management sequencer to gate the output. Fixed output means no external resistor divider — the BOM count stays low.
