3.6 V fixed output, 150 mA — what the ratings mean for the BOM
PSRR runs 80 dB at 10 Hz and rolls to 52 dB at 1 kHz. Dropout voltage maxes at 1.4 V at full load.
Protection set and control
The TPS70936DBVT carries over-current, over-temperature, reverse-current, and under-voltage lockout (UVLO) protection. Reverse-current protection is unusual in a 150 mA LDO and matters when the output rail could be held high by a backup battery or a bulk capacitor while the input collapses — the regulator blocks back-feed into the supply. The Enable pin lets a system controller gate the rail for sequenced power-up or sleep modes without an external load switch.
